Along with publishing to AIR, you can also do what is called publishing to a Windows and Mac Projector file.

In File > Publish Settings, you should see a number of check boxes. Down the bottom are the options "Win Projector" and "Mac Projector". Tick those, click "Publish" and then your file will be exported. The file size bumps up a few MB (I think it's about 1 or 2, can't check) as what it's doing is bundling the Flash player within your application, so even computers that don't have Flash can run it (which is handy if you made a presentation or something).

The projector runs much like your Flash file in the end. I don't know if it's good or bad practice to even make these projectors, but the option is there.
