I have a 2007 workbook that used to have a reference to the MS Project
12 Object library. I recently installed Project 2010 and now I get an
Object library invalid error whenever I open the file. I get the
error regardless of whether macros are enabled, and the error pops up
so much I can't close the file without using task manager. I do not
see any missing or broken references. I have deleted any code that
initiates MS Project. The file continues to work well on a computer
with only Project 2007; of course the export to Project code no longer
works, but, I can live with that. I jst need it to function on the
computer that has Project 2010 installed; without the reference to
Project.

I have deleted all references except
Visual Basic for Applications
Microsoft Excel 12.0 Object Library
Microsof Office 12.o Oject Library

I can create an run macros on this machine; when I open the file that
previously had a reference to Project 12 and has been "upgraded" to
Project 2010 is get overwhelmed with Object library errors. I don't
have any more ideas.

Any suggestions?

Thanks
