Re: Sims 4 Won't Work on Vista??? The demo works fine.

It's included in the minimum specs. I don't work for EA so I'm not going to give you any guarantees.

EA does have the great game guarantee though. If it doesn't work, you can give it back within 24 hours. You just need to buy it through Origin.

I also can't see why the demo should work on Vista but not the game.
