...trying to install VFP6 on a machine where VFP5 is already installed.
All of the computers at DevCon had both versions of VFP (5 & 6) installed on same machine. AFAIK, there is no problem have both versions (or all 3, VFP 3,5,7) installed on the same machine assuming you have sufficient disk space.
