Re: sims 4 updates verifying game files
This is what I did.
Put your Saves, Tray and Mod folders and Option.ini file on your desktop (from Documents, Electronic Arts, Sims 4). Delete the rest of the The Sims 4 folder from your Documents > Electronic Arts folder. Then start the game, exit the game, and copy then paste your moved items back and say yes to overwriting the files. Delete the Scratch subfolder from inside Saves. Then start the game again. If you are still unable to start the game (which happened to me), go to your game icon (if in Origin, in "My Games"), right click and select "check for update". It should reload the update and then it worked for me.
If you haven't played the game at all, you could probably skip moving the saves, tray, mod, and option.ini folders, and just uninstall the game, reinstall the game, and then check for updates. Hope this helps. If not let me know or if you need something explained more clearly. Good luck!
