Put a setup.exe for a "hello world" app on the server; that one would install vfp6 runtimes.
Have a launcher which is named as your old vfp5 exe, and have it check for the existence of the VFP6 runtime on the user's box. Then use Ed Rauh's API_AppRun class to run the setup.exe if the runtime is missing, or run the real app's VFP6 executable if it's already there. Then quit the launcher. Launcher should be a VFP5 exe, so it would run on any machine which was able to run the old app.

You'll notice that there are a few details missing here - first, at the moment I don't know how exactly to detect the presence of VFP6 runtimes. There should be certain files in the windows' system directory, but don't have the details at hand. Second, there was some trick to build a setup which would run silently, but I don't even remember which tool did we use to build it - it's been two years ago. Still, all this didn't take more than few hours to make, and it worked flawlessly.
