Vista MUI Solution With Vista MUI Tools

First of all, I would like to say thank you to Same Frank, who has been so helpful and kind to provide his step by step guide on using Vista MUI Tools v2.2.

Vista MUI Tools v2.2 is a freeware developed by Nice-Repair.com, a non-official Microsoft product, to apply Windows Vista Ultimate Language Pack for multilingual feature on non-Ultimate editions!
This tiny freeware is only useful and work on non-Ultimate Vista editions. The MUI pack is not included as its purpose is merely to automate the process of applying the extracted MUI files on non-Ultimate Vista editions. Thus, you’ll have to manually download the Vista MUI pack for your language from Microsoft server.
The text and guide below are comment posted by Same Frank on “Download Windows Vista Ultimate MUI Installer”. With his consent, I’ve decided to make his comment as a new post, to make way for follow-up related to Vista MUI Tools.

Posted by Same Frank, on 3rd of March

It took me a few days to sort out the problems listed below and am now happy to post the official download link and my notes on installation.

Direct Download Vista MUI Tools v2.2
Download latest Vista MUI Tools v2.55, as informed by Same Frank.(Thank you, Frank!)

This program helps install additional MUI Packs to all versions of Windows Vista and allows users to select their own language interface.

Although the program has been fully tested, it is still in beta stage. Users are strongly advised to back up their system before using this program.

Install Notes….Before you run the program, you must:

(i) Enable Administrator Account, and logon as Administrator (see below)
(ii) Disable User Account Control (see below)

Install Steps:

1. Unrar the file to C:\Windows Vista MUI Tools v2.2\folder
2. Make a C:\MUI\folder, put the downloaded MUI pack in this folder.
3. Run Windows Vista MUI Tools v2.2
4. Choose Method 1, click Install
5. EXE2CAB Choose Input File is the exe MUI file in C:\MUI\folder
6. EXE2CAB Choose Output File is the C:\MUI\folder
7. The MUI exe file will be converted to MUI cab file, when completed, click Install again
8. Click the MUI cab file and click open, installation will start
9. Installation will take up to 15-20 minutes
10 When completed, a confirmation box in Chinese will pop up , click YES.
11. Another pop up in Chinese asking you to delete temp files, click OK
12. Wait for the cleaning process to complete,(5-10 minutes)
13. Choose the newly installed language in Select Windows Vista Language,
14. Click Apply, click OK/Yes, then restart through start menu.
15. Vista starts in new language.

Enable Administrator Account

1. You can enable Administrator account by right clicking My Computer>Manage>Local Users and Groups>Users, and then right click Administrator>Properties…untick the account is disabled box, click apply, click OK, then log off and log in as “Administrator”. You can disable this account by re-ticking the box.

2. Or run the net user administrator /active:yes command (without quotes) from Start>All Programs>Accessories>command prompt, right click command prompt, in the pull-down menu choose Run as Administrator, then key in the command, when its finished, log off, the Administrator will appear alongside your own account, log in as Administrator.

Disable User Account Control

Click Control Panel, User Accounts, you will see the option “Turn User Account Control on or off”, turn it off (by unticking the box).

Windows Updates, Windows Sidebar Problems

Most of the problems will disappear after a few reboots. If the problems persist, you can use these solutions:

1. Windows Update may not work properly in the new language. Download this Microsoft Hotfix –Update for Windows Vista (KB947506)—in the new language, turn off UAC, and run it. After its completed, reboot.

2. Windows Sidebar may not function. This problem was caused by Update for Windows Vista (KB943411). Download this update for the newly installed language, use winrar to unrar it, and look for the 2 files (Sbdrop.dll.mui and Sidebar.exe.mui) in the language folder (for example en-US folder).Then copy the 2 files to the Program Files\Windows Sidebar\xx-YY folder (xx-YY like en-US) and reboot.

Unable to select new language

If you run this program by logging in as Administrator with UAC turned off, this would NOT happen.

If after running the program you know you have installed the MUI pack but are unable to click the Apply button in Select Windows Vista Language, log in again as Administrator and turn UAC off and try again.

If problem persist, then you can try to modify the registry key

to read as

and created a string value inside it :

DefaultFallback = “xx-YY”

(where xx-YY is the existing language, aa-BB the new language, ie English is en-US, German is de-DE…)

    Thank you Walker for this great job!

    Just an update on the Windows Update problem. The Hotfix can only be run by logging in as Administrator with UAC turned off. Otherwsie, it will return with an error message saying resource center cannot find any MUI.

    The Windows Update problem is a hard nut to crack. Most people who change their language manually cannot get it to work. When you run Windows Update in the new language, it opens a blank window with all icons and text missing, and you cannot go further.

    I have re-tested it this morning and the Hotfix works beautifully. MS knows how to torture people who did not go by the book.

    Hope this helps.

  2. Walker 07-03-08@02:03

    Hi Frank, thank you for the updated guide again.

    BTW, could you please comfirm the direct download link is the correct KB to fix Windows Sidebar malfunction issue?

  3. Same Frank 07-03-08@07:38

    Hi Walker, yes it is the direct download.

    But I think people should also be given the chance to read about the release notes. at the link below:


  4. Walker 08-03-08@04:45

    Frank, you’re right.
    I almost forgot the importance of reading KB release notes.
    You’re great!

  5. Same Frank 14-03-08@05:25

    Just another update.

    Thanks for the link.
    There has been hundreds of downloads since this post.
    I am sure lots of people find it helpful.

  6. Paco 16-03-08@03:28

    Hi Frank,

    when I get to the step 8, I get an error message. The window is called “Information” and then I get another error message with the error 0x80070057. Do you know what I can be doing wrong?

    I have followed every step with no problems, but when I get there I cannot install the .cab file.

    Thank you very much in advance


  7. Same Frank 16-03-08@15:04

    Hi Paco,

    I think this is a parameters error when the file path folder is made up of one of more spaces.
    Try put everything in the C;\MUI folder (copy all files in the C:\Windows Vista MUI Tools v2.2 folder to the Mui folder, include the MUI pack ) and run the tools there by right clicking the tools file, and in the pulldown menu chhose Run as administrator.


  8. Dimi 17-03-08@08:49

    Hi Frank,

    I have installed everything successfully but in the following step
    13. Choose the newly installed language in Select Windows Vista Language,

    I select the new language (Greek) but the Apply button is grey out not selectable..

    Thanks Dimi.

  9. Paco 17-03-08@23:32

    Hi Frank, it worked! Thank you very much!

    By the way, when selecting the new language, I had to select English (American because with the English (UK) the Apply button was grey out not selectable. I suppose both must use the same file, so I let you know just in case someone has the same problem.

    Thank u again, and kind regards,


  10. Same Frank 18-03-08@16:39

    Hi Dimi,

    You can try the part on changing registry. Or run the program by right clicking the installation, and in the pulldown menu, choose Run as administrator.


  11. J 18-03-08@17:45

    Hello, great stuff. However, I cannot get started as I don’t have the Exe2Cab program and there seems to be no working url from where to download it. Does anyone have an idea where to get it?

    Does it have to be this program? Or are there other possible alternatives?

  12. Dimi 18-03-08@22:14

    Hi Frank,

    I tried the registry change, but I had two entries there el-GR and en-US. So I removed the entry en-US rebooted and it worked Greek Windows!

    The Windows Update and Sidebar are functioning properly without any updates or hotfixes.

    I will post if I see any new issue.

    Thanks for your help.

  13. Same Frank 19-03-08@06:34


    Thanks Paco and Dimi for the feedback, Really appreciated it.

    And J March, just download the tools (see the direct link above).
    The EXE2CAB file is included in the program folder.
    As for you other question, this is the only working program apart from the one that I posted in the PB forum (which made use of WAIK, a MS tool too large to downland and handle if I may say so).


  14. naeco 25-03-08@13:28

    Hi Frank,

    Thanks a lot for the guide, I managed to change my Vista French version into English successfully.

    However, I have a problem switching back to original language. When I launched the program and selected fr-FR (the original language), it wouldn’t want to change it back (apply button remains grey).

    Can you guide me through this one?

    Thanks a lot ! Keep up the good work !

  15. Same Frank 26-03-08@20:43

    Hi Naeco,

    Try logon as Administrator, turn off UAC, and run the tools by right clicking it, and in the pulldown menu, choose Run as administrator. See if you are able to use the Apply button now.

    Or, as one user suggested, run Regedit, and see if the key:
    is present (if not, create one)


  16. naeco 27-03-08@19:17

    Hi Frank,

    I did try the things that you mentioned but it did not change back to original. I tried uninstalling the MUI files, then I couldn’t read the texts in windows anymore (file name, shortcuts,…)

    Any idea why?

  17. desmo 01-04-08@06:55


    I tried everithing reported here … but it’s not work: error 0×80070057

    I tried to change the language from Spanish vsita home premium to italian home premium …

    It start to install but after 30-35% it’s block …

    I tried different version of the tool and I also tried what you racomented about the folder, ec… I also download the Microsoft patch …

    I have Vista withot SP1 … any Idea?

    thanks in advantage

  18. desmo 01-04-08@06:56

    sorry the error error 0×80070057 now it’s not appear more …

    but like first It start to install but after 30-35% it’s block …


  19. Same Frank 02-04-08@20:49

    Hi Desmo,

    I think it was probably due to permission problems. First log in as Administrator, then turn off UAC, then run the tools by right clicking the file, choose Run as administrator in the pulldown menu.

    You can also try to force-install the Mui Pack as follows.
    After Exe2Cab converted the Mui Pack to a cab file, rename it to Lp_it.cab and put it in a newly created C:\Temp folder. Open command prompt as Administrator and run the following command:

    Start /w pkgmgr /ip /m:C:\Temp\Lp_it.cab

    This will hopefully install the Italain Mui and will enable you to switch to Italian.


  20. Same Frank 20-04-08@17:22

    Hi Guys,

    I have repacked the latest version of the Mui Tools and the installation guide.

    You can download the new version here:



  21. Walker 20-04-08@22:52

    Hi Frank,

    Thank you for the prompt update.

    Btw, what are the features or fixes included in this latest repack?

  22. Same Frank 21-04-08@00:57

    Hello Walker,

    The repacked version is v 2.55. All dialogue boxes can now be displayed in English as well as Chinese, and it includes separate tools for x86 and x64. It is also compatible with Vista SP1.

    Some users reported mistakes in running the program because they did not log on as administrator with UAC turned off. I have thus rephrased the installation guide to make these points more apparent.


  23. Walker 21-04-08@12:16

    Hello Frank, you’re the man!

    Thank you for the efforts.

  24. Orion 24-04-08@17:03

    Hi Frank,
    I`m trying to change my Vista Japanese version to English. I have the same problem of someone. However i use run as Administrator the Apply button could not be clicked. In the registry, there was only ja-JP. I created en-US and restarted but it was in vain.
    Could you guide me to solve this problem?

    Thanks for your work!

  25. Same Frank 30-04-08@16:14

    Hi Orion,

    Pls download the new version from the link above.
    Run the program again and when its finished, DO NOT reboot.
    Use regedit to open registry and you will probably see both ja-JP and en-US
    Delete the ja-JP entry and then reboot.

  27. shaman 19-05-08@22:40

    Hi Frank.

    I’ve installed and changed the language from Japanese to English successfully however I can’t seem to change back to the previous language. The apply button for Japanese is greyed out and not clickable.

    I used the MUI Tools 2.55. In the registry there are both en-US and ja-JP. I’ve turned off the UAC and used the Administrator account.

    Please help.

  28. Xris 20-05-08@00:57

    Hey there,
    I can’t get it to work on my EN Vista Business (MSDNAA) version to change it to German de-DE.
    I get all the steps including no12 but I can’t select anything. No languages, nothing. The apply button is grey and not active. (v2.55 x86)
    I have tried numerous times now, with regedit and so on. The last time I needed to repair my system because it ran into a bluescreen loop.
    BTW, is the value to be added in the registry in doublequotes or without it?
    I think that might have caused my bluescreen (Yeah, I crashed Vista!!).
    I am loged on as the administrator with UAC off.
    Any suggestions?


  29. Lee 20-05-08@02:09


    Managed to convert my copy of Vista from German to English thanks, just having problems getting windows update to work correctly again. keep getting the following error mesage (Installer encountered an error: 0x80073afc, the resource loader failed to find MUI tool)

  30. Same Frank 21-05-08@22:43

    hi guys,

    you dont need to run the hotfix. the windows update problem will sort itself out after a few reboots.
    as for japanese, the program has a small bug which greys out the apply botton. use registry to add or delete ja-JP entry and then reboot.


  31. Xris 22-05-08@01:49

    Hey Frank,
    I managed to get it to work somehow. Thank you!!
    One more thing: Is there any way that I may use the control panel to change back to EN if I wish to or do I have to use the Registry?

  32. Andy 22-05-08@07:54

    Having trouble changing language under Vista SP1 x64.
    Says “Regretably! Installation failed!” When i try to install the new pack.
    Trying to change from english to swedish using the official SP1 mui pack. I’m in the admin account with UAC deactivated.

    Same Frank: you should consider making the tools open source :)

  33. sinan 24-05-08@02:32

    after a few tries i used regedit and that worked perfectly for me…
    though… when you make the change in the registry when you change the name xx-YY to aa-BB do not forget to remove the already existing key aa-BB there… you might crash your comp. i did so in the first time :o)

  34. Shanw 29-05-08@10:59

    The link for download for ‘Direct Download Vista MUI Tools v2.2’ is not working. Is it possible to update the link or provide another alternative download link?

    I happen to passby same frank newer version v2.55. It seem not as stable as the earlier v2.2 do correct me if i am wrong.

    Thanks in advance

  37. Walker 24-06-08@15:25

    Rex, the link is still valid, except now the link requires user to register and login before the file download begin.

    Please take note that that link is provided by Same Frank (and I believe that’s reliable source that maintained by Same Frank).

  38. Walker 24-06-08@15:35


    Please refer to Same Frank comment, the latest Vista MUI Tools can be sourced from this link too:


  39. Michael 17-07-08@18:34

    Hello Frank、
    Im using 2.55 and I guess the issues reported by some people regarding certain languages like german greek japanese are due to a small bug in the language select dialog of the MUI tool. Such languages internally in the registry use codes like de DE or ja JP aso., while the MUI tools tries to set and check for a none variant code like de or jp only.

    Thanks for the tool

    thanks, walker and frank! genius!

  43. Walker 03-09-08@10:18

    Sorry for belated reply.

    I didn’t know that good Same Frank emailed me the updated download link of his MUI Tools v2.55.

    So it’s here:

    Download MUI Tools v2.55

  44. Walker 03-09-08@12:03


    I’ve just tried to download that latest MUI Tools v2.55 from the updated link provided by Frank, but my Kaspersky alerted me that’s trojan program.

    I’m not sure the RAR file has been infected after Frank uploading it. I’ve email Frank to check this out. While waiting for his reply, Please don’t download the MUI Tools.

    I shall update you the status. Stay tuned.

  45. Walker 04-09-08@01:29

    OK, Frank has confirmed the RAR file being clean and green.

    The MD5SUM between the attachment sent by Frank and the RAR file contents downloaded from rayfile.com are identical:

    Also i can no longer access User Accounts as administartor or as a user, I have successfully changed from spanish to english, thanks.

  48. Walker 06-09-08@11:45

    Hi Tom, both KB947506 and KB943411 hotfix links are working as I tested them just now.

    You may also source them from Microsoft Update directly.

    Hope this help.

  49. Tom 06-09-08@18:45

    The problem I have is when I click on the links or go to microsoft update directly when it tries to download the file it just gives me a blank address not found screen and does not work. I´ve tried to find the hotfix from another soure with no luck, also I have tried to reboot several times in order to see if this resolves the update problem but with no luck. Would this also be what is stopping me from accessing user accounts? i have read elsewhere that some people have also suffered this problem, thanks for your help!

  50. Tom 07-09-08@00:42

    Sorry to keep posting nut i´ve managed to get the hotfix KB947506 from somewhere else as a standalone installer but now I get an error message 0x80073afc failed to find MUI file, what is the resolution for this

  51. Same Frank 07-09-08@15:31

    Hi Tom,

    Pls turn off UAC, then right click the hotfix file, and in the pulldown menu, choose run as Administrator…

    Good luck

  52. Tom Fong 08-09-08@13:12

    I have followed all the steps and they all seem to work fine. Then I go and try to add a Chinese input device, but the option to do that is not there in the “Regions and Languages” control panel. Is there a way to get it to show up? Many thanks!

  53. Same Frank 09-09-08@17:17

    Go to Control Panel, Regions and Langauges, Keyboards and Languages, then choose Change Keyboards, the input methods are all there.


  54. Tom Fong 10-09-08@06:28

    Hi Frank,

    Thank you. I never thought to look there.

    Another question if I may. There are a few programs (e.g. qq from http://im.qq.com/qq/dlqq.shtml) do not display properly. Instead of displaying Chinese characters, it displays ‘??’. Is this related to MUI?


  55. Walker 10-09-08@22:31

    Hi Tom, you may try to set the Windows Vista default system locale to Chinese for non-unicode Chinese program to “appear” better.

    Hi Walker,

    Thanks for the tip. My laptop already had the system locale set to China. so I uninstalled qq, rebooted, and re-installed qq. The same result happened. I also have a desktop running xp professional with language packs. There qq displays properly.

  58. Same Frank 14-09-08@21:42

    Hi Youyi,

    Try the tollowing steps:

    1. As Walker says, go to Control Panel, Regional and Language Options, Administrative, and change the system locale to Chinese (PRC)

    2. Also in Regional and Language Options, Administrative, in the lower part on reserved accounts, click copy to reserved accounts, and tick both default user account and system account

    Reboot .


  59. Teil 16-09-08@09:15

    First, THANKS A LOT !!

    I downloaded the latest V3 from http://www.nicety-repair.com/ as I’m Chinese and can read Chinese on that forum :) The installation/process was flawless on this new version and the English version was indeed transfered to Chinese version — V3 is a dummy version although I did follow the instructions here very carefully, thanks to Nicety, Walker, & Frank!

    HOWEVER, I quickly realized several problems, and after googling, I saw other people reported exactly the same problem with ealier versions (V2.2/V2.55). The problem includes several basic functions in vista that stopped running completely (just nothing happens):
    1) The “personalize” menu (Right click on desktop -> personalize)
    2) The User accounts
    3) Windows update (no errors, a window popup for milliseconds then disappears)

    Other users reported the same problem, i.e. http://www.mydigitallife.info/2008/03/06/vista-sp1-multilingual-user-interface-mui-language-pack-install-tool-for-business-home-premium-and-basic-edition/

    Following the suggestion here, I first rebooted the PC about 10 times, no change, so I supplied the hotfix (KB947506), still no luck after several reboots :(

    It’s almost a brand new preloaded Vista Home Premium, with Symantec vista antivirus loaded.
    I’m trying to get this vista into Chinese so my mom could enjoy a world of technology at her old age, without the struggling with English that she never encountered; so it’s actually almost OK even with those problems, but I’m still wondering whether I did something wrong, or it’s a bug??

    Many Thanks, Again!

    Sorry for the mess, but do want to update on the problem reported above, it’s a good news !

    Couldn’t fell asleep last night, so I reinstalled the whole system, Vista Home Premium SP1, before installing ANY application software, including antivirus, I loaded the V3 with method 1 and tried again … … EVERYTHING IS OK !!!!!

    I do not quite understand but probably some software messed it up before (?), or I myself did something wrong.

    Anyway, this is a great tool, and many thanks again!

    Walker: you may just delete my posts then, sorry for the mess :p

    Good day Teil, thank you for your follow-up comments.
    It’s really useful for others to read the “start and end”.

    Hi all.
    In my case operation failed with error 0x80070057.
    Tried to install English or Spanish Mui packs on a Portuguese Vista Premium with SP1 using v2.55. Couldn’t get it to work. UAC is off.
    By the way I had some trouble activating the administrator account: There is no entry in the MMC console for Users and Groups and turns out the account name is itself localized. So the command that worked for me is:
    net user Administrador /active:yes
    Can you help please?

  64. Luis Faim 25-09-08@00:31

    Ok. This has NOT been easy!
    So, I managed to install en-US. Problem was either using pre-SP1 MUI pack or working from D: instead of C: . Computer rebooted and interface is now in English.
    Apparently pt-PT installed too but is not apply able i.e. has no (exist) tag in front. I’ll try the reg hack next.
    Now I see that this procedure doesn’t enable the Display Language switch in Regional And Language Options dialog box!
    What I’m trying to do is have an administration User profile in English and 2 other User profiles in Portuguese. Can it be done?

  65. Icecold 04-11-08@11:50

    hello I am having the error : regrettably! installation failed! I done everything on the manual including the regedit step, but i always get the same error, could you please help me, by the way I am using the latest version of the software 3.0.

    Hello Walker and other:
    I am sorry to post this comment but now I am having troubles with my windows vista home basic. I bought my laptop with Japanese windows and I decided to change the language to English. I followed all the steps described in this site. However, I was still not able to click the apply button because it was grey out. I was so excited to see the other solution in this site. I edited the registry

    The stupid thing I did is that I did not read carefully the last line and did not add the last line: DefaultFallback = “xx-YY”

    As a result my windows vista home basic is down now. Actually I have two windows. my windows xp is still working. I wonder if I can use my xp to undo my vista registry . Thanks for any advise.


  67. Walker 11-11-08@21:58

    Hi Rico, sorry to hear about your case.

    You may try to boot up with Vista CD and use “Repair Your Computer” options, specifically “Startup Repair” for recovery.

    To be frank, I’m not sure this could help or will this lead to data loss if not properly used, but this is something I can think of now.

    Maybe Frank or others can give you a hand.

  68. Same Frank 12-11-08@16:01

    Hi Walker,

    In Rico’s case, it may also be that the installation was not completed. Normally you don’t need the fallback option.
    One way to try is to boot into safe mode (keep pressing down the F8 key when computer boots), choose last good conditions and this would hopefully undo the registry change.


  69. Walker 13-11-08@00:44

    Thank you, Frank.
    Thank you for reminding me the F8 options.

  70. dc 07-12-08@09:20

    I followed all the steps and it says failure file not converted, press ok to exit.

  71. Rico 09-12-08@11:41

    Dear Walker and Frank:

    I am so sorry for my late reply because of my busy work. I have tried to use the F8 options. But it still did not work. I think now the last choice is to use the recovery CD, which I try to avoid.

    If you have any other solutions, please kindly let me know.

    Thank you very much.


  72. Martin 16-12-08@02:11

    I have tried all sorts with this. I can’t get it to work. Tried it on administrator account with UAC off. I get to stage 3 (Language Pack Installer) and then after around 5 minutes I get the message Regrettably! Installation Failed! or something along those lines. Tried in safe mode and such.

    Would really like to get my version of Vista converted to Spanish.

  73. Petyyy 18-12-08@15:06

    Hi! I got that “Regrettably! Installation Failed!” message too (Vista Business 64bit with SP1 ) . Any idea? :(

I dont like them to install automatically. after about one month i was unable to start Control Panel -> Updates. It is showing half disabled window without any language strings shown. If i try to open properties of wuauserv service it again complain about MUI file ( looks i need reinstall windows. any suggestions? thanks.

  83. Same Frank 09-02-09@13:54

    Hi Mangust,

    I suggest you use Vistalizator 2.0.1 instead which is more stable and more user friendly (download it here http://www.froggie.sk/ ).

    The windows update and control panel problems only appear in the new language and in Vistalizator it allows you to switch back to original language to install all the updates including the hotfix which must also be in the original language.

    In my test case for Visalizator, I switched back to the original language, installed hotfix (which said update not installed but in fact all the files were copied to their right places), removed windows search 4.0 (as I was running sp1), rebooted and rand updates in the original language, installed all the updates, and finally used Vistalizator to remove and reinstall the second language.

    When I rebooted to the new language again, windows update and all the control panel icons were working.

    Hope this helps.

    Hi Frank,
    thank you so much for an excellent programme. I installed the English language pack no problem, switched it over to English and then used that for a week or so, switched back to the computers orgional language to install any required updates, ran the computer for a few days before I switched back to Engligh and when I did the updates were working fine in the new language.

    One question: some of the features in the new language, like Device manager are still in the origional language. Is this common?? It’s only in one advanced feature that i noticed so far as as luck would have it, it’s one i’d like to change the features of.

  85. Same Frank 21-03-09@20:08

    Hi Micheal,

    I think the author of the programme has come up with a solution, by reinstalling Windows Update Agent and Windows Search (for the new language) within the programme itself.

    You can download the latest 2.10 version (which includes these fixes) from the link I posted.

  86. Raymond 23-03-09@07:47

    Hi Frank,

    I have followed the steps

    i) Enable Administrator Account, and logon as Administrator
    (ii) Disable User Account Control

    Install Steps:

    1. Unrar the file to C:\Windows Vista MUI Tools v2.2\folder
    2. Make a C:\MUI\folder, put the downloaded MUI pack in this folder.
    3. Run Windows Vista MUI Tools v2.2
    4. Choose Method 1, click Install
    5. EXE2CAB Choose Input File is the exe MUI file in C:\MUI\folder
    6. EXE2CAB Choose Output File is the C:\MUI\folder
    7. The MUI exe file will be converted to MUI cab file, when completed, click Install again
    8. Click the MUI cab file and click open, installation will start

    When I reach this step I received an error message named “pkgmgr”
    saying “Windows cannot find ‘pkgmgr’ . Make sure you typed the name orrectly, and then try again”

    When I click “Ok”

    I receive another message named “information”
    Congratulations! the installation is complete. You want to remove the temporary files?”

    After I have restarted but it is still in the language which I purchased my desktop with

    Hi Raymond,

    I suggest you use Vistalizator instead, which is more effective and stable.

    Hi Walker,

    Thanks a million for this.

    BTW, the latest version of Vistalizator v2.30 also works for Windows 7.
    So if you like to change the language of your Windows 7 Home Premier etc, just download the tool and the related MUI from the links here:

    I’m having the same problem as a lot of people are having, and I don’t see any response, or attempted response, by you guys to resolve the “Operation failed with 0x80070057” issue. I followed the steps precisely, I am running as an admin with the UAC turned off and ran the command line “net user administrator /active:yes” and then followed your instructions exactly to a tee. I have been trying to install Japanese on my Vista Notebook.

    Here’s what happens:
    1st: everything is going smoothly, I click install, select the package, convert it to a cab, select the cab.
    2nd: window pops up saying language install kits require 5-20 min (blah blah blah blah)
    3rd: before i can ever finish reading the window the error window pops up (as mentioned earlier) then i click ok
    4th: after that it says installation complete would you like to remove the temp files/folders? yes/no and then acts like it installed it. restart has been attempted, no change in language or language options in the control panel.
