I have a vast amount of Sims 2 games that will not install onto my new laptop. My laptop is a lenovo yoga 2 pro with windows 8.1 I believe. It will let me install the very first Sims 2 game (the orginal edition), but it will not install any expansion packs such as Sims 2 Pets or Business. I was hoping someone could help me out and tell me what I need to do or if it is possible to download the game from the internet and just using the passcodes that came with my games.
