>>>Using the setup wizard in VFP 3.0 the installation gives error that it can not open the MFC40.DLL file. If ignored the installation will install from a later diskette. Question I have is what does the MFC40.DLL have to do with installation and why is VFP 3.0 assuming this file already exists. (only happens with computers early version of Windows 3.1)

Ronald,

MFC40.DLL is the Microsoft Foundation Classes DLL. According to a Quick View in Windows 95, it's a 32 bit DLL. That explains why it won't be found in Win 3.1. As to why VFP 3.0 is looking for it, I can't say.
