HELP : Launching external file not working

Hello,

I tried to apply this tutorial to my projector but somehow it’s not working.
http://www.kirupa.com/developer/flash5/projectorcommands.htm

In my projector, a button would launch a DIRECTOR MOVIE named “Projector.exe”. This is how my script goes:

on (release) {
fscommand (“exec”, “Portfolio/Projector.exe”);
}

I already checked the path and the locations of my file. And everything is in the right place. To check it out more, I tried to launch a Window application just to make sure the script works but it didn’t.

on (release) {
fscommand (“exec”, “C:\Program Files\Winamp\winamp.exe”);
}

What am I missing in here?

Thank You
