Hi Allen.

>>Thanks for your help. I'm still trying to solve the mystery. <<

Good luck. And please let me know what it was when you solve it.

>>Yes, but when I look at the other computer I find it's running VFP3.0 (which shouldn't make any difference since I'm installing an EXE) and the version of GRAPH5.EXE is older than the copy included in my setup. Maybe it's a version problem and the older GRAPH5 was not overwritten with the newer GRAPH5. I'll do some testing on that... <<

You did say that this worked fine on your development machine but not as an executable on the target machine, right? This definitely points to something in the environment. You just have to figure out what it is.
