Re: Sims 3 Supernatural has been "installing" for hours!

Can you close Origin ?

If so, do that and restart and then see what it says on MyGames.

If the game then doesn't work, remove everything Supernatural from your computer following instructions here: http://simswiki.info/wiki.php?title=Game_Help:TS3_Uninstall and here: http://answers.ea.com/t5/The-Sims-3/Help-Guide-All-in-one-fix-except-hardware-issues-PC-only/m-p/734448#M36281 where it says Delete game installers

Then try installing again.

You just need to do it for Supernatural.
