running out memory when run a window program from powershell even though the program runs fine if not running from powershell

I have a window program. If I double lick it in window folder and run it, it works fine. However, if I try to run the file from powershell script, it will run out of memory. how should I do to fix this problem? Since I have many test cases that run the window program, so I do want to run all of them from script.

Thanks
