Mike,
Since your VFP app runs in the context of a regular user, it is not allowed to WRITE into the ProgramFiles tree. That's a standard Windows Security feature since Vista. For older software, which does not adhere to those security guidelines, those write attempts are rerouted to the "VirtualStore", so that the old software does not generate an error. The regular user/application does not see any difference, since the "VirtualStore" is an overlay to the real filesystem. Only if you look with activated Admin-Mode, then you see a difference.
Each user has it's own VirtualStore area, you find it at %Appdata%\Local\VirtualStore\
(You know that you can use Environment variables like %temp% or %Windir% directly at the Explorers path textbox?)
wOOdy
