I finally wrote a VB application to launch files from a flash presentation. You can download it here:

This application will open files in the associated applications. You can also specify a optional installer incase the user does not have the required application to open your file. You can do this globally using a text file or by individual file. Download to find out how..
Note: Tested in Windows 2000 and Windows XP
