Trouble Installing

Hi there,

I'm having difficulties installing Adobe Air 4.0 on Windows 7 Home Premium 64 bit

I've tried everything I can think of, that includes the Microsoft Fixit thingy and removing all programs I can think of that depend on adobe air

(side note, I've uninstalled the version of adobe air I had installed so it's no longer showing up in controll panel)

Install.log - Truncated to the last install attempt:
