Why is EA making me redownload sims 4??

StrawberryMilk10 Smelllikemel  Where was your game installed previously?  If you're not sure of the exact path, please at least let me know whether it was on your C drive or a secondary one, especially an external drive.

If the game has installed a second time, and you want to make sure you don't have duplicate installs now, please open a File Explorer window, click This PC in the left panel, and search for TS4_x64 .  If you see more than one result, list their locations.
