I have seen contradicting documentation regarding which versions of MS Office that MSGP 2010 will work with. I suspect that Microsoft prefers users to be running at least MS Office 2007, and preferably MS Office 2010. However, I can't imagine that MSGP 2010 would actually be "incompatible" with MS Office 2003. My best guess is that it sacrifices some functionality, but still co-exists. Does anyone know the details of this situation? Do potential users of MSGP 2010 have to upgrade to Office 2007 or 2010 in order to successfully install MSGP 2010? Or, is there documentation available somewhere that specifies what you sacrifice in features and functionality by remaining on Office 2003? Thanks.
