Re: Change language in the sims 3

@RulleMarie89  If you've installed through the EA App, the only supported way to change the language is to uninstall and reinstall the game.  When installing, you'd choose the language here (screenshot is Sims 4, but it's the same for Sims 3):

If you can't install in Danish, please post a screenshot of the languages you do see.  If you can choose Danish but the game installs in English, please let me know.
