If you are on Mac Catalina please check out this thread "The Sims 4 macOS Catalina Troubleshooting" .
Open up your task manager and click "more details"
If you see Sims 4 is open, close it.
This should work.
hi, i have no idea, i run sims on windows 7.
i still havent found a fix.
Also running SiM on Windows 7 SP 1, getting the same error. I uninstalled sim , origin, and ran a service pack update , took origin out of the start up folder ....
** SAME ERROR this has to be a bug in the game, where are the EA people to fix this!!!!!!!!!!!!
Try holding down ctrl+alt+del at the same time on your keyboard. This will open the task manager.
Windows 7 will give you a blue screen where you can choose the task manager. See if TS4.exe is running, if so force stop it.
If you're getting this error Sims 4 is already running - ed35e0ea:29f00e76:00000000:18a1dd51
Please post about it in the Sims Mac Board -

Some technical issues need to be handled differently because they both are running different operating systems. Mac computer don't have Task Manager, but they probably have something similar.
