>>>The control will be in the Windows\System or System32 (on NT, I think) directory. If it is there, it should be registered. If you have doubts, that's when you need to check the registry. That's the easiest way to tell if the user has the control. In general, the installation program will install the control, and warn if the version on the target machine is newer than the one being installed. You can, however, do this chore manually by using AGETFILEVERSION() in VFP 6.0 or the foxtools GetFileVersion() in VFP 5.0 and comparing the version numbers (in the fourth array element) against each other. To register the control you can RUN the REGSVR32.EXE with the /S parameter to register the control if you copy it to the user's machine.

Certainly,

The reason I'm not using the setup wizard is that I want the .app file and the data to reside on the server and have the users open VFP ( again, on the server ) to run the .app file ( on the server ).

The app uses the M$ Comm control to dial the phone via modem so the control must exist on each PC even though the application does not, correct? No, wait... since VFP's running from the server, the Comm control only needs to reside on the server... Hmmm, I'll try this approach...

I've never been able to settle on a solid approach to multi-user apps so I would be interested to hear how other do it. I've used .exe files and .app files both local and on the server. Which is "best"?

TIA
