I have a Flash Introduction that autoruns when the cd is inserted. How do I
make the CD menu program (CD_Start.exe) run when the intro finishes or from a
button at the end of the intro? I have tried using getURL but it only opens the
root directory of the CD in IE.

I am new to actionscript.

You can use the exec fscommand. Something like this:

fscommand('exec','CD_Start.exe');

But, I'm pretty sure you need to put the CD_Start.exe inside a directory
named: "fscommand" due to security issues...
