PSTools PsExec Help

[Azerex]

So I have a web server setup on a remote windows machine using wamp. I am trying to run this php script and have it open the file on that machine:

<?php
    exec('C:\Users\*user*\Desktop\PSTools\PsExec.exe -accepteula -i -s C:\wamp\www\Titanium.exe', $output);
?>

This code causes it to indefinately hang. Any suggestions?

So I was messing around with the code more and I tried moving the PsTools directory into the wamp server and the calling it from the new path. This now does not cause it to indefinitely hang however, it still does not run the intended program on the remote computer.
