>Is it possible to have two versions of VFP, 6.0 and 9.0 loaded on the same machine? All of my apps I have used 6.0 for development. I have just purchased 9.0 and need to move all my projects to it and re-build the exe files.

Yes. I used to have VFP6 - VFP9 installed on my PC w/o any problem. Make sure that they don't share foxuser.dbf. Keep in mind that all VFP file extensions will be associated with the version installed last.
