>I'm currently working on a small launcher program in .NET that would eventually launch a VFP executable. Is there any reasonably sane method by which I can prevent execution of the VFP executable by any means other than by the launcher? In other words, the user should not be able to start the VFP executable by clicking on it.

Just use a parameter in the startup program and if the exe is not called with your special startup code, then quit.
