Hi,
I have an MFC application running. When end user clicks on a button it should launch another application (.exe). I have used CreateProcess to do that with environment settings also. I tried with _spawnlp() and spawn versions also. But it is launching some times and it is failing some times. What could be the problem. Help me out

It sounds like your logic (not the CreateProcess call specifically),
so you haven't given us enough information.
