Topic: Autoviewer playable in Flash7?

I know it says Flash 8 but is it possible to make Autoviewer work with Flash 7?  I ask because Flash 8 is pretty new and not many of my clients/potential clients have their computers that updated.  And yes, I know they can just download and install the new flash when the detect page comes up.  But I know that most people will just say screw it and close out the player.
