Enchanted by Nature not showing as installed

I've purchased the pack via EA App on my PC and it says that I own it but haven't installed it yet. According to my purchase history the game has been paid for. Even my map in game says I own it but haven't installed it. Where do I need to install? I primarily use the EA App though it doesn't have any links or a way to update available. The website also doesn't appear to have an easy place to find it. Any help would be appreciated.
