Adobe AIR download issue

Hello,

I'm trying to download the newest version of Adobe AIR and, upon launching the installer, I keep getting a pop-up message telling me that "this application requires a version of Adobe AIR which cannot be found.  Please download the lastest version of the runtime from http://www.adobe.com/go/getair, or contact the application author for an updated version."

I've read through the online troubleshooting, and either I'm not tech saavy enough to figure it out or my issue wasn't listed.

Please help.

I'm on my MacBook Pro, OS X 10.7.2
