Problem with folders after reinstalling Sims 4

@Caerfinon Yes, I tried reinstalling the game a couple of times, as well as the EA App in general. Everytime, the EA App puts the Electronic Arts folder in the same spot next to the EA Games folder under Program Files, and I can't seem to chose another location for that.

When I try to move the Electronic Arts folder later, I get the notification that I can't since 'a file is opened somewhere'. However, all programs and the EA App are fully closed (in the background as well)...
