Problem When I try to start the game, I get the following error message: Unable to Start: Origin is not running, make sure that it is running before attempting to play the Sims 4 [d3382ced:984c6a38:00000000] Cause The Sims 4 needs the latest version of Origin installed. This message is very common if you upgraded to Windows 10 (or if you run an illegal version in which case you’re out of luck) Solution Uninstall your current version of Origin and download the newest one from here: https://origin.com/download. Then install that. If you’re still having issues, do a manual, clean uninstall of Origin…
This error is most often caused by incompatible mods. It can also be a corrupt installation.
