Origin not running (d3382ced:984c6a38:00000000)

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]

OriginNotRunning

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

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.
Where can I find my installation folder ?

Windows now has a lot of security measurements to make sure external programs don't harm your computer. This can be the reason that the game doesn't have enough rights to execute a function and it gets blocked.

You can find the files for Sims 4/Origin here
