    When opening office programs (word and excel) user recieve the following error:

    C:\Documents and Settings\username\Applications Data\Microsoft\AddIns\C:\Program Files\Common Files\Microsoft Shared\Geography\mpoai9.dll' is not a valid Office add-in.

    OK is the option, and when clicked, the requested document opens.

    This appears to be a MapPoint addin, but when I try to remove the add in, there are none listed. Any thoughts?

    That is one of the things that I tried, yes. But when I get to the Add-In box, it is empty making it difficult to remove and get rid of the error.

    Also tried removing the MapPoint Add-In directory in the registry, after rebooting, it shows up again.

    I'm afraid I haven't used Add-Ins enough to be of much more help. :(

    Have you tried to re-install the Add-In and then trying to remove it?

    It is a MapPoint add-in from what I can tell, and the user does not have MapPoint installed. Nor do we wish to install MapPoint.

    After talking at lenght with Microsoft, we did the following to correct the mpoai9.dll error:

    Saved the current registry.
    Opened the registry
    Find: mpoai9.dll
    Deleted (from the right side) all values with the error.
    Worked!

    I found the errors under the follwing:
    Outlook
    Visio
    Word
    Powerpoint
    Excel
    Internet Explorer
    Publisher

    I was also getting a Windows Installer when opening an Office application; that was corrected by reinstalling Office.


    Thanks! I hope this helps someone as much as it has for me! :D :D :D
