Just a quick post in the "please remember this" section.

If you ever have problems installing Adobe AIR applications on Windows Vista because the .air extention is not recognised, do a "open with" and find the executable located in "Program Files/Common Files/Adobe AIR/Versions/1.0/"

I was suprised this info took me a few minutes to find, especially as this (recently updated) Adobe knowledge base article simply states "This is a known issue on Windows Vista and there is currently no solution"


WTF? that's the most stupid answer ever: there's a solution for EVERY problem.
Sometimes a  solutions might be a bit extreme, or end up being worse then the problem, but not in this case: simply browsing to an executable yourself is just fine.
