I have a couple of VFP apps running as services, so it will work
fine.
1) Are you using pview to see if your exe is really running?
2) Have you tried logging errors to a text file
3) Does the app run fine on the same machine as a standard exe?
4) If so, check the user account that the service is logging in as, in
Control Panel -> Services -> Startup
5) If your app is calling OLE or advanced functions, you will need to log
the user in with sufficient rights (a standard service is limited in access)

Just a few things to shine some light...
