I installed VFP9SP1 update on one PC and VFP9SP2 update on another PC. It did ask for original RTM media though.

>I downloaded and attempted to install the SP2 (actually, I have the 1st SP2 with the goofed logo) and I got the following error message from the installer:
>
>"This patch package could not be opened. Verify that the patch package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer patch package."

>Great! I'm running off my C drive.

>I'll try installing on my home machine, but I'm not too optimistic.
