Ok, so I downloaded the Sims3 create a world tool, but when I try to install it it says " This Product requires an installed copy of the Sims3. Please install The Sims3 before installing this product". I do have an Offical copy of the Sims3, I bought it through Steam( And the Showtime Expansion). So why is this happing?
Community AdminThe CaW Tool does not recognize the Steam version / installation. My advice would be to un-install the Steam version and download and re-install the game from Origin. Just make sure that you keep your saves.
The topic is old, but this was the first result I found online for this specific problem (i'm on windows 11 x64).
The solution was provided by James Turner in a video : Sims 3 101 - Install Create A World for Steam
