Sims 4 Error: Already RunningThis error usually means that the computer seems to think It's already running Sims 4, even if it's not. Here are some tips to help with this error:
1. Fully exit out of the game and Origin. - If exiting Origin isn't working, open Task manager (Ctrl-Shift-Esc) search for a file called ts4.exe. Click on it and select end process.
2. Shut down the computer by clicking the Start button > Shut Down. Then turn it back on and try launching Origin and the game.
3. Try resetting the Sims 4 folder - aka Sims 4 Factory Reset
Rename your current Sims 4 folder to Sims4Backup. Launch the game and create a new save to test. - Without anything added back, especially the Mods folder.
If it's not working, don't save. However, if everything is playing okay then start putting the files back from the backup folder. (list of files and folders below).
- Options.ini (User game settings)
- Tray Folder (Sims/Houses/Commercial lots and rooms)
- Screenshots/Videos/Custom music
- Rest of the save games, if any.
* (leave out slot_00000001.save which is the autosave. It is not used anymore.)
- Custom content like clothing, hair, skins, and makeup
- Mods (Put these back one by one to make sure they all still work)
