Re: I reinstalled the sims, chose Norwegian but it shows in English

People had said it many times. Uninstalling and reinstalling the game won't change the language. I want to play in Polish, yet the only language available to me upon installation is English. 

@GreyHavens85  You have a language-locked version of Sims 4, which is limiting your options.  People with the global version can uninstall and reinstall in a different language without problems, at least most of the time.

If you'd like to play in Polish, you can try contacting EA customer support to ask that the English-only version be removed from your account.  As long as you're not currently in England, which I believe is the only country that receives the English-only version, you should get either the global version (all languages) or the Polish/Czech/Russian version.

The other option is to install Sims 4 through Steam, which only offers the global version.  You'll need to uninstall the EA App version, install the base game through Steam, then install your packs through the EA App, but NOT a second copy of the base game.
