Well, you don't have to install VFP on the target machine.
If you are running with a .exe file - you can mostly just copy that. Exceptions would occur if you added features that encompassed additional controls, fonts etc.
That aside, the answer generally is to make the target machine check a source to see if the version being run is older than the source and if so download the source file first.
Plan B is to ALWAYS down load the source first - regardless.
