Re: Sims 2 Legacy Won't Launch

That sucks. Before I did the above, I also updated my drivers including my Nvidia driver as well as:

Open Windows Settings > Apps, scroll down to the Microsoft Visual C++ Redistributables, and uninstall everything from 2015 and newer. Don't touch the older versions.

Download the x86 and x64 versions (not the ARM version) of the 2022 runtimes from Microsoft:

Install the runtimes, restart your computer, and try to play.

Have you tried those?
