xman_iceman Sims 3 runs fine in Windiows 11 most of the time. There's no particular reason why it shouldn't run on a given Windows PC. What happens when you try to play, that is if you already own at least the base game? Please describe what you see, and test again now if it's been a while.
Please also provide a dxdiag. Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
