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]
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)
Uninstall your current version of Origin and download the newest one from here: http://origin.com/download. Then install that.
If you’re still having issues, do a manual, clean uninstall of Origin by following instructions here: Manually Uninstalling the Origin client and then try to install the newest version again.
You won’t loose your games by uninstalling Origin but you temporarily can’t play them. Make sure to login with the same account after reinstalling.
Other things to try
- Scan your system for viruses
- Start the game as administrator
- Start the game in compatibility mode
- Try a Clean Boot.
- Make sure the TCP port 3216 is open.
- Last resort: Switch back to 32 bit
