ActionScript 2.0 :: Using FSCommand To Execute External Apps?

Basically I'm trying to use fscommand to open programs outside of the flashplayer. This I thought would be pretty simple but apparently not.Here is the actionscript I've already tried:

Code:
on (release) {
fscommand ("exec", "C:UsersMattDocumentsflashMTRXfscommandpin.bat");
}
on (release) {
fscommand ("exec", "fscommandpin.bat");
}
on (release) {
fscommand ("exec", "pin.bat");
}

But guess what, on release nothing seems to happen.The SWF file is in the folder "MTRX". I'm using Flash MX 2004. This is what the BAT file is:
Code:
@echo off
start PinballBot.exe
When I open it from windows explorer that works.
