Sims 4 unable to open error message

Hey, I've had sims4 deluxe ed on my pc for quite a while, and felt like installing it right now, but after installing i get the error message.
not sure what that means? I have no other sims or origin in my pc

That means you had newer version installed previously. If you don't care about previous saves - go to "Documents\Electronic Arts" and delete "The Sims 4" folder. If you do - update your game. The fastest way is by updating it with my repack. Patch alone weights 3.6GB. After you install it the game will work. https://www.games4theworld.club/t33925-the-sims-4-alternative-installer-v2-download-only-what-you-need-even-smaller-than-before
