Hi Bill.

>On a Vista machine, install your executable in a subfolder of the APPDATA folder rather than Program Files. It appears that APPDATA is the place designed for this purpose.

Don't do that. Executables should not go into a folder that users can write to. Doing so opens a huge security hole on their system; malware can easily insert itself into an EXE or hijack a DLL and do whatever it wants when the app is launched. That's why there's a Program Files folder and why it's read-only.
