Most likely there is some kind of bug in register.exe. Can't really tell without seeing the source code of course.

Does register.exe run OK when you run it alone?

Does your program crash when you replace the line with, say,
retval = Shell("c:windows
otepad.exe",1)
?

Hopefully this will help you narrow down the source of the problem.

Don't know why, but running the .EXE on the E: drive may be causing a problem. Try moving the .EXE to your C: drive and see if it still happens.

As I say, don't know if it will make a difference, but there may be a problem with the CD-ROM drive (assuming, that's what your E:Drive is)

i tried to make the path for the .exe file the same as the applicaion, but no go. i will try and move it to the c: drive.this problem also happens during design time (run mode) as well.

still no go.......
i have checked through the code and its ok......just found that it only occurs when i move my mouse pointer over one of the text box windows.one contains the serial number and the other is where the user enters the unlock code. the first one is the culprit.
i dont know why though ???

Obvious question: does the registration program have any code in the mouse_move event for that textbox?

no it does not......and i have checked the code again and there is no sign of it causing a problem.
