my sims 4 wont reinstall

@itztrickyxx  Did you uninstall the game from the control panel - programs and features? You need to uninstall before you reinstall. Usually the core game is ok but the user data causes the issues so no uninstall/install is needed. To reinstall the game you need to uninstall the game, clean the registry (use ccleaner - there is a free version), move the user data to your desktop, install the game. To set the game to factory setup, all you need to do is move the user data from the documents folder to your desktop. Doing this will make the game like you just installed the game and create a new user data folder. The installer does not know of any files created after the install. Therefore the uninstall wizard does not know of the files and therefore these files will not be removed by an uninstall.
