>I want to have a VFP 7 exe check for existence of the VFP 9 runtimes on a workstation, and then install them if they are not there. Next it would either copy and then run, or just run a VFP 9 exe. When I test this I get strange results. The program works as intended, but it appears that the VFP 9 exe is running in the VFP 7 runtimes and that the VFP 7 exe continues to run.

Calvin,
If you call it with "do myApp.exe" you're still in the context of the caller. Use ShellExecute API instead.
Check http://fox.wikis.com/wc.dll?Wiki~VFP9RuntimeFiles
However I suggest you to create a separate install for VFP9 version.
