The upgrade adviser told me my computer was compatible. I bought the upgrade, downloaded and found out it wouldn't install. My computer is too old, missing some CPU feature (NX if my memory serves, possibly not). I am certain I don't have the feature - I checked, in every possible way. I'm fine with it - I figured I'll eventually buy a new computer. The thing is, now it seems I'll be penalized for Microsoft's misdiagnosis of my computer unless I rush to buy a new machine, and get it by the end of the month. My searches show it's impossible to get the upgrade otherwise. Please show me I'm wrong...?
