I’ve followed the instructions in that post you linked, and there are no signs of any packs in the Windows Registry. However I am still not able to uninstall the base game as it says ‘I have one or more packs installed’. I was wondering if OP found some way of finding hidden files using Revo Uninstaller that wasn’t mentioned in that Mod The Sims article.
@Violett7799 , do you still have an EA Games folder in your Documents? If so, drag it to your Desktop and see if that then allows you to install the game.
