I’m creating a promotional CD that will be handed out to lots of people - which means mostly pc and macs. I know in flash mx you can publish both a windows projector and a mac projector. First, how do I detect if someone is on a mac or pc and second, how do I then play that type of executable off the CD? I do not want to run this through as an html file. Please help!

Thanx
