Why would I want to fix windows?
So you can run SoaSE.
The only reason I have windows on my computer is to play Sins of a Solar Empire
So if you can't run SoaSE on it, it's time to fix it. Reinstalling should work fine.
Sins of a Solar Empire runs great on Ubuntu!
That's great!
Does it matter that it's "unsupported"?
Yes, as you just explained:
This word just means Stardock does not necessarily pay staff to ensure it runs on unsupported operating systems.
Bingo.
Impulse does not run at all on Ubuntu!
Because it's not supported.
I am not cheap, I have more money than most people in my age group.
That's nice, but irrelevant.
This makes my dissatistifaction with a company's products more important.

No, the world does not revolve around you or your money.
I own five computers and own more than five copies of windows.
So use them for something other than doorstops and quit whining.
I am absolutely computer literate, have built my own computer from scratch, am fluent in several programming languages, etc, etc..... by principle and habit, I prefer linux.
CS major, know several languages and programming styles, A+ certified, have built several computers from scratch, not impressed at all by people who think superior knowledge and/or skills somehow demands special treatment.
