Failing to run

Tarryn_Higgins​ I found two threads that might address your problem you might want to look at them and see if they can help you find answers for you issue. 

Graphics card not recognized | EA Forums - 12236976

You have to manually get the game to recognize your graphics card which is very much possible through editing it yourself, because it might be new and unknown to the old sims 3 program. If you get in contact like the pop-up says maybe they can do it for you. 

Tarryn_Higgins​  Please 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.

Please also open DeviceConfig.log, in Documents > Electronic Arts > The Sims 3, copy the first 40 or so lines (stop at Options), and paste them into a reply.  You can delete your user and computer names, about 20 lines down; the file doesn't contain any other personal information.

It's not going to help to get your graphics card recognized if your GPU isn't even being used, so the first question is what the game is using.

I'm having a similar issue, i got a legion windows 11 laptop and everything is showing fine till i try to start a new game/new world.. stops me saying something went wrong

Thank you so much 💛

Tarryn_Higgins​  This dxdiag and DeviceConfig are from the newer laptop, right?  The latter shows that while Sims 3 doesn't recognize your graphics card, it's able to use the GPU, so that's not the cause of the issue.  I can try to help with the hardware error on the older laptop, but it sounds like that's a moot point if you can get the game running on the newer one, so let's start there, that is if you're having trouble playing.  Are you still seeing the initialization error, or is there some other issue?

Meanwhile, to test a number of possibilities at once, please create a new admin Windows account on your newer laptop.  Make it local, as in, don't link it to your Microsoft account or any email address.  Give it a simple name (like Test) with no special characters in it.  Try to play while in that account; you won't need to reinstall anything to do so.  Let me know how it goes.
