link to .exe to install program

so Ive got a cd that runs the standalone flash player on startup. In this flash presentation are links to some programs that people can install; the install files for these programs are in folders on the cd. Right now Im using the following to link the button to the install file:

on (release) {
fscommand("exec", "aasim\\setup.exe");
}

where the flash file is in the root of the cd, and aasim is a folder off the root. Ive tried this a few ways, single slashes, back slashes, etc., I just dont know enough flash to know what Im doing wrong. Any ideas? Should I not even be using fscommand? I know VERY little about flash, so simple answers are appreciated...
thanks

if you're using flash mx, the file to execute must be in a folder called fscommand. it might be your problem
