Setup cannot find Office.en-us\ShellUI.MST in MS Office Pro Plus 2010 and Windows 8


  • Greetings all

    When I installed MS Office Pro Plus 2010 in a Windows 8 64-bit. Received the following message:

    I downloaded another copy of it assuming that it is corrupted and still encountered similar issue.

    I installed the x86 and x64 version of MS Office and still encountered similar issues.

    Details are as follows:

    OS: Windows 8 64-bit

    Current Office Version: MS Office 365 Home Premium Trial Version(OEM)\

    Want to install: MS Office 2010 Pro Plus

    Please advise.

  • Hi,

    In a similar case, the issue is related to the permission on C drive. Check it here:

    Determine if we have the full permission on the computer to install the software on C drive.

    I verified if I have the permissions to install the software on C drive and yes, I have. I am a member of the Administrators Group. Similarly, I even encountered this on a Windows XP PC when trying to install MS Office Pro Plus 2007, the same error message was seen.

    Further checks online, made me found the following article:

    Realize that the software was purchased in France and what was being shared to me was a French version of the software. My computers are all set to EN-US as the system locale. 

    Tried both workarounds that was stated in the article but still came with the same error message:

    1. Change System Locale to French, restart and run the setup again - Failed with similar error message

    2. Check the config.xml file and notice that EN-US is already added as a language.


    <Configuration Product="ProPlus">

    <AddLanguage Id="fr-fr" />

    <AddLanguage Id="en-us" ShellTransform="Yes" />

    I located the folders Office.en-us and and found the ShellUI.MST file in this folder.

    Please advise.
