Using the RegEdit program (enter that name in Start-Run) look for the key:

HKEY_CURRENT_USER\Software\Microsoft\Office\Excel\ Addins

Under it you probably will find the key "MapPoint.OfficeAddin.9". This is
causing your problem and deleting it should fix it.

| Hi,
|
| I am running Office 2003 on the terminal server (windows 2003) and had a

| files\common files\microsoft shared\geography\mpoai9.dll is not a valid

that
