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.
You need to update the Sims 2 games that have been installed, only then will you be able to install all other Sims 2 expansions.
The patches are in the link below, patch the first game and work up to the most recent game:
