Hi Jwcga,
I stumbled upon this thread, after looking through the job post on guru.com. Not sure, if you have posted it or someone else.
Can you tell me, why are you looking for it to get listed ? I have Windows 8, but I too don't see it in the list directly. There are many dll files.. "Adobe AIR.dll", I can see while searching.
May be you just need to test an AIR based application or game. If it works fine, then it means Adobe AIR has installed successfully on your system.
