Wiliam,
I had the same problem on my Mac running OSX 10.4.11 (Tiger). It sound
like an MS OFFICE PROBLEM that I had. same error message It was
happening in Word and Excel.
First, try this:
In the Finder, select a Word or Excel document, then press Command
(Apple) + i to bring up the Info window. Expand the Open with section of
that window and select the appropriate application from the dropdown
list. If Word or Excel are not visible, choose Other and navigate to the
application. After selecting the correct application, click on Change
All, then check if the application now launches correctly.
If that doesn't do it, try this (this is what cleared up my problem)
The Test Drive is known to cause problems, and if your problem does not
go away, it might be a good idea to remove Office and the Test Drive and
to reinstall Office afterwards.
To remove Office properly, go to Applications/Microsoft Office
2004/Additional Tools/Remove Office.
Drag the "REMOVE OFFICE" application to your desktop. Run it from there,
then delete the ALL Microsoft Office 2004 versions, including Test
Drive, in your Applications folder and proceed with the reinstall.
Good luck.
