Can't install Air on OS X 10.7.2

I am on a MacBook Pro running 10.7.2, and I am unable to install Air. I get one of two scenarios when I try to install. I either get absolutely no interface, error message, or anything else, or I get an error saying that a newer version of air is require (But how am I supposed to install a new version of air if it needs a new version simply to install?!) When I receive the latter error message, these are the log messages that are found in system.log:

Any help is appreciated. I was able to install air on OS X Lion a few weeks ago, but now I'm having the most frustrating time with it. And the adobe support documentation has not been helpful.
