AIR installation constantly fails

I cant seem to get the AIR application to install properly. Ive had releases 05 and 06 on my machine, but now I cant seem to get the latest version. I am getting an error message saying that insatllation might not be allowed by the system administrator. THis is on XPSP2 and Im logged into an admin level account. I have removed the AIR runtime from Program Files\Common Files\Adobe AIR and the user specific setting folders from Application Data and Local Settings in my user folder, but the install still fails everytime. I even tried logging into my machine as another user to see if that would work, but no dice.

I really want to get this working properly because I know that I wont hit the website as often as I would run the app on my desktop. AIR looks like it will be a good platform, but its got to work properly for it to get any foothold. And of course I had no luck checking Adobe for assistance...their support and forums have never been very helpful IMO.

Hopefully someone out there has an idea how to fix this.
