 * On Windows, you must set the read & execute permissions on C:\Windows\system32\cmd.exe for the account the PHP web service extension is running under. PHP needs those permissions to "fork" other process.
 * If using WAMP (and possibly other stacks) on Windows, you must set the "wampapache" service to "Allow service to interact with desktop".
