Intro and Problem

Hi everyone. Happy to have found my way here. I am an avid fan of the Sims 2. I have all the Sims games and feel that Sims 2 is by far the best of the lot. However....I just purchased a new computer with windows 10 installed and I have been completely unable to install my old games. I'm looking for help with this. I have every single expansion and game pack...I can't believe I'll never again see Brandy!
