In your code example, this is missing. So do you actually have a 
waitForStarted or not? It's vital, because proc.start() will immediately 
return and your proc.state() compare will fail because at that moment 
the process is NOT YET running. In fact in this moment it is most likely 
in QProcess::Starting state!

No, I mean it doesn't work if I use the WaitForFinish function instead of the state check. 
ie: instead of the while loop, just use the WaitForFinish(some time) function.
