I booted into Safe Mode and it was still just my normal account.
And my account was always admin before and I never had a problem installing software. I turned UAC off so it just did whatever it had to do to install.
Ah never mind, I had to log out of my normal account with Safe Mode, click on Administrator, then make a new account with admin rights, then log in as THAT one and make myself a member of Administrators.
Good riddance, though.
