I was wondering if I am doing something wrong or something, because I bought Sims 3 supernatural online off origin and I downloaded it and everything but now it just wont install first it is saying Please use The Sims 3 Launcher and update your version of the Sims 3 before installing this product.

Sorry to hear that you are having issues @salt-James.
Can you try launching the game by bypassing the Sims launcher:
Let me know if it works.

@salt-James How did you originally install the base game? (disc, Origin; hopefully not Steam) If this is a disc install, did you ever patch it? An Origin install would come fully patched, unless it's more than five years old. (Also, please don't try to patch an Origin install; you might break it.) And are you running Windows or macOS?
