The Sims 1 won't launch – tried everything
The Sims won't launch – the screen flashes, and EA App opens again. I tried clearing the cache in the app and resolving compatibility issues in the game files, but nothing helps.
To everyone in this thread, please try reinstalling your 2015 and newer VC++ runtimes. 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:
https://docs.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170
Install the runtimes, restart your computer, and try to play.
If that doesn't help, please provide the information requested in the accepted solution of the master Sims 1 won't launch thread:
