It's critical to create a new folder into which you install the game, and the folder cannot be in Documents or on the desktop. If you use a third-party antivirus, please disable it temporarily while reinstalling the game, and don't reenable it until you've tested Sims 4 at least once. As long as you don't do anything else at the same time, your computer should be safe, and you can reenable the AV after you've tested.
