Uninstalling Sims 3

I installed the leaked version to see if it was good enough to buy. It came out today so I decided to; but whenever I try and uninstall the game that’s on my laptop now the game launches and the setup freezes. Any ideas on how to get the game to uninstall without starting up? Thanks in advance.
Answer #1
Try using a third party uninstaller like Your Uninstaller.
Answer #2
Well, I got the RELOADED one uninstalled by letting the game start up, exit after it finishes loading, and the the game started uninstalling. (I may have gone through the cycle twice.)
Answer #3
I had the reloaded 1 installed a friend dled and installed on my PC, so while it was there I checked it out then uninstalled it
got the Sims 3 Collector’s edition installed and now it keeps telling me my copy is the un finished copy in the lancher and I went through the registry and deleted all about the Sim 3 after I uninstalled the Reloaded copy and tried installing and un installing the retail copy and keep getting same thing about it being unfinished copy in launcgher, anyone else have that prob after using the leaked copy and getting the retail cop and what to do to fix that?
