I have done now further investigations on the problem with START_PROCESS@ and Error 740.

The app which should be started by START_PROCESS@ has an UAC symbol in its icon and the "Properties" of the app have no "Compability" tab. So I can't remove this administrator privilege.

Even if I delete the app and rebuild it, I get the same behaviour.

This appears only for the 32-bit release of my project.
The 64-bit release is working without problems.

I am willing to do some testing if you can provide some code that illustrates the failure. I am assuming that you are using Windows 10.

Paul,

I have sent an example to your e-mail address.

Paul,

I have solved the problem by using ShellExecuteEx. I have build a small function START_MY_PROCESS which works like START_PROCESS@ and has no problem with my examples.

If you are interested in the solution, I can send the source code to you.

Thank you. That would be useful.

I am using START_PROCESS@ in FTN95 v8.0 with no problems. 32-bit calling 32-bit, on Windows 10.

Never heard of START_PROCESS_AND_WAIT@ - how does that differ, if at all, from START_PROCESS@ where the calling program waits for the called process to finish?

They serve the same purpose and are coded in much the same way but START_PROCESS_AND_WAIT@ is for Windows (e.g. ClearWin+) applications where an internal "temporary yield" is required in order to process the Windows message loop.

Thanks, Paul. My 'parent' application is Windows/Clearwin+ and START_PROCESS@ works just fine (The 'child' process is a command-window program). But maybe I should really be using START_PROCESS_AND_WAIT@ -- will try it and see if it runs any differently!
