Unable to open .docx files after conducting March 2010 Microsoft Update

    Hello -- I'm running Windows 2000, MS Office 2003 Professional, and Office Compatibility Pack. My system has been running quite stable. In conducting the March Microsoft Updates, it updated with the following files:

    Security Update for the 2007 Microsoft Office System (KB978380)
    Update for the 2007 Microsoft Office System (KB977724)
    Update for Microsoft Office Outlook 2003 Junk Email Filter (KB979771)
    Security Update for Microsoft Office Excel 2003 (KB978474)
    Windows Malicious Software Removal Tool - March 2010 (KB890830)

    After conducting this update, I find that when I attempt to open a .docx file, I get "There was an error opening the file." error message. I went into Add/Remove Programs in Control Panel, but was unable to find KB977724 listed. I tried removing the Office 2007 Compatibility Pack and downloading it/installing it fresh, but to no avail.

    Any suggestions would be greatly appreciated.

    Thank you.

    I have the exact same problem and have been unable to find a solution.

  4. Can you two open up a case as not seeing any other calls on this right now.

    I did open a case: Support Request Number - 1127134209

    As for your question on having 977724 installed, I don't know how to verify, other than going onto Microsoft Update, reviewing my update history, and it showing that I successfully installed 977724.

    (via Google web search for
    KB977724 site:microsoft.com inurl:technet

    KB980210 supersedes KB972224.

    Perhaps you should be checking out that one instead? At least it has a KB
    article which hints at the modules involved. ; )

    Because it isn't a security update there is no TechNet Security Bulletin
    info which would be a customary secondary source of info about patches.

    Otherwise, if you do have it installed perhaps you have a KB977724.log
    file which would give you some clues about what all it changes?

    Per my history, I too have 977724 installed. It does not, however, show up
    under Add/Remove Programs.

    I have not had the time to open a case as I am working on a deadline.

    Check that out
    Susan Bradley, Mar 12, 2010
  11. Same here:
    MS Office 2003 Professional
    Office 2007 Compatibility Pack

    Failures appeared immediately upon installing this month's patches, which
    included updates to the Office Compatibility Pack.

    This bug manifests on only the computers on the network which have not
    been upgraded to Windows XP. The XP computers on the network with the
    same software installed are not affected.

    Watching this thread and hoping for a solution.

    This is not an isolated incident, I have had the same issue as of March 10th.

    It seems it affects users who are:

    1) on Windows 2000 OS
    2) Are running Office 2003
    3) Have had the three security updates installed as of March 10th.

    I too have a case number (1127128725) which has been no help whatsoever.
    The aforementioned link also does not solve the issue as it is for a Server
    oriented OS.

    It seems to me that Microsoft should rectify this issue as it is clearly
    their patch that created the incompatibility issues.

    We have the same issue. There is also an issue of being unable to open
    (convert) .xlsm files. This only occurs on our Windows 2000 PCs with Office
    2003 & the Office 2007 Compatibility Pack.

    977724 updates MSO.DLL in

    C:\Program Files\Common Files\Microsoft Shared\OFFICE12

    977724 does not show up in Add/Remove programs, but I was able to find an
    older version of MSO.DLL in the Windows Installer patch cache:


    To verify that the problem is caused by the MSO.DLL from 977724, I renamed
    the MSO.DLL in

    C:\Program Files\Common Files\Microsoft Shared\OFFICE12

    & copied the MSO.DLL I found in the patch cache to the above location. I was
    then able to open (convert) .docx files in Word 2003 & .xlsm files in Excel

    The version of MSO.DLL installed by 977724 is 12.0.6521.5000 & is dated
    10/29/2009. The version from the patch cache is 12.0.6425.1000 & is dated

    I tired installing the hotfix from


    It does NOT fix this issue.

    That is a great find. I installed a previous version of the MSO.DLL which
    has also solved my compatibility issue.

    For informational purposes, others who are having an issue can try replacing
    the MSO.DLL mentioned in Sam's post with this one which is also version


    Hope this helps.

    Microsoft should immediately issue another hotfix to resolve this issue so
    we as consumers don't have to dig around and patch together solutions like
    this on our own.

  18. Would you guys mind sending me a sample of an impacted file that you
    can't open?
    Susan Bradley, Mar 12, 2010
  19. KB977724 wasn't one of the March 2010 updates anyway.

    These updates have also broken Office 2002 on Windows 2000 although the error
    is different- "This is a pre-release version of the compatability pack.".
    I have mostly office 2002 but the few Office 2003 machines I have started
    producing the "error opening file" message on the same day (12-03-2010).
