Game not launching, Windows 10

OldeSimsFan​  My game still runs fine on Windows 10, or at least it did as recently as a couple weeks ago.  So I doubt the issue is the OS by itself.

Anyway, 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.

Thank you.  Will give it a go when on that machine.

Here you are.  I hope it helps.  Even after the latest update it won't launch on Win 10

OldeSimsFan​  Your dxdiag is full of crashes of Dropbox, which I wouldn't usually expect to have anything to do with Sims 4.  But is Dropbox trying to sync your Documents folder or anything inside?  If so, it could be locking up the folder and preventing the game from writing to it, which would in turn prevent the game from loading at all.

Point is, kill Dropbox and any associated services in the Task Manager, including in the background processes list, before you try to play.  If they're set to open with Windows, they'll open again the next time you restart your computer, but they should stay disabled in the interim unless you open Dropbox manually.

Aside from that, your computer's graphics driver is from 2018, which could also explain why Sims 4 isn't working.  Nvidia offers a much-newer driver (2024), so try installing that:

Run the installer as an admin: right-click the download and select "Run as administrator."  Restart the system afterwards and before trying to play.

If you happen to get an error that the driver isn't compatible with your hardware, that's just Dell software blocking drivers not provided by Dell.  (The driver is compatible with your GPU.)  Let me know, and I'll describe how to get around the error.
