>An old (and almost forgotten) client I wrote a plant management system (about 4 yrs back) for in VFP 5 called and asked if I could make some modifications. My VFP 5 in on a 486D in my closet, so I asked that they download any VFP5 SPs and mail them to me with their VFP5 license [since mine must be in storage, or lost].

Making the mods in VFP7 and providing an installation CD is not an option? There is no problem installing VFP 5 on the same machine as 6 and 7. You can still get the SP from http://msdn.microsoft.com/vfoxpro/downloads/updates.asp
