PHP exec无法正常工作

Question

I'm running Apache 2.2.17 and PHP 5.3.5 on a Windows 7 64-bit machine.

I have noticed that if I try to use exec(), system() or any of the other functions for executing a system command through PHP it does not work. The exact same commands will work if you paste them into the command line window. This seems to affect all programs which are not the simplest of command line programs. Even a simple attempt to open notepad will not work e.g. system('C:/Windows/system32/notepad.exe').

What could be causing this?

Thanks

Unfortunately none of these solutions worked for me. I have changed my approach and will not be using PHP to launch the executable.
