That's most likely the problem, I have XP but from what I've read about Windows 7 it "protects" you from damaging your software by pretending to install things in one place, and actually installing in a secret virtual folder someplace else. You will need to find someone to guide you through setting up the UAC permissions, how to install the game, how to use "run as administrator" for things like Content Manager. I can't do it because the only thing I know about Windows 7 UAC is all the confusion I have read about, I have never actually used it myself.
