This fixed my problem and made the R6025 runtime error go away!

I assume that changing that LoadBehavior value from 3 to 1 stops it from
loading when Excel 2007 is launched. While making this change, I noticed
there were a few other add-ins for Excel that had been added by other
software I've installed. All of my other Excel add-ins seem to working fine,
but I'm guessing there might be other Office add-ins that might cause a
similar problem for other users.

Does anyone know of a list of Office add-ins that may not work with any of
the Office 2007 applications?

If you receive this error:
"Microsoft Visual C++ Runtine Library"
"Runtime Error!"
"Program: C:\Program Files\Microsoft Office\Office12\EXCEL.EXE"
"R6025"
"- pure virtual function call"

Then you must do this:
Start Run : regedit (then click OK)
\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Exce l\Addins\RCMSOExt.Connect
There, i opened "LoadBehavior" and changed the Value Data from 3 to "1". I
click
on Ok, re-ran Excel and now its working fine.

If you need me to go into more detail on how i did this, let me know and i
can do the breakdown.
