Re: Sims 3 Late night says unknown error

There might be some kind of problem in the installation of the game. Please, try to follow these steps:

1.- Manually uninstall The Sims 3 Late night

Go into Applications > The Sims 3 and drag The Sims 3 Late Night (EP03) to the Trash (including the Readme.txt file). Don’t forget to trash any shortcuts you have created too, including ones on the Desktop or in the Dock.
Now you must delete the residual file that the uninstaller has left behind. Make sure you are in Finder and click Go in the menu bar. How down the Alt/Option key and click on the Library folder that appears in the drop down menu. Once you have opened it navigate to the following locations and trash the files/folders in red:
- Library > Preferences > The Sims 3 Preferences
- Library > Caches > com.transgaming.thesims3ep03
- Library > Cookies > all files starting with com.transgaming
Go back into Applications > The Sims 3, right click on The Sims 3 game icon and click on Show Package Contents. Navigate to Contents > Resources > AddOns and drag The Sims 3 Late night to the Trash.
Open Origin, then go to Origin > Preferences in the menu bar, then go to Installs and saves. Then click on Browse installers and delete The Sims 3 Late night installer if it's still there.
Empty your Trash.
Launch the game from The Sims 3 base game app in your Applications > The Sims 3 folder. You can check that The Sims 3 Late night has properly uninstalled because it will no longer be showing in the Launcher, it will be greyed out.
