And seeing what happens on the console when it tries
If you can't see anything there, then redirect the output and error streams of the process to either a stream in your app or a file and see if you can see any error messages there.
You need to get error (or otherwise) messages before you can even begin to diagnose the problem, and we really can't do any of that for you!
