@Qkaender Do you mean .NET Framework 3.5? That's what Sims 3 uses, and that hasn't changed.
At any rate, please run a dxdiag and attach it to your reply.

And if you see another error message, please post a screenshot of it.
Yeah, I mean 3.5, sorry for the confusion. I did the DirectX diagnosis. In fact, the system was with the DirectX12 version. Again, I don't know why my computer changed the .NET and DirectX, there were no changes these days, only the update for Sims 3, there wasn't any new game or app that required a change or something. Weird, but now the game is working.
