I'm tring to get this to work. I had it on my old machine, but I just got a Windows 7 upgrade. I downloaded AIR no problem and I have the zip file. The only files in the zip are the mimetype and a swf. Isn't there some sort of executable or something to install?
This may help. This was sent to me by one of our listeners that had issues with windows 7.
