I suddenly started getting error 1309 (file is not an object file) on a client's machine--actually several machines at the client site. I am not getting this error on my machine or on other clients' machines.

In my architecture, the system starts off with an exe. The exe then calls the main .app file. It is when the exe calls the .app file that the error 1309 occurs.

However, I first got this error when I installed an updated app that is called by another app. That call also failed with the 1309 error.

I tried to correct this problem by rebuilding the exe file and the main app file (both in VFP7 SP1) but the error persists. Does anyone have experience with this problem?

VFP6 Help says 1309 indicates an attempt to execute a compiled VFP program that doesn't have a proper header.

Is it possible that there's some strange thing at this one client that is causing this problem?

Thanks
