If you try to install straight away it will tell you that you need to have Sims 3 installed and installation will fail as the Create a World tool does not recognise the Steam version of Sims 3’s installation. I have followed the steps outlined in this guide and it has worked for me without any issues however you make these changes at your own risk!įirst, download the Create a World Tool from The Sims 3 website -> Link *WARNING!* Making changes to the Windows registry incorrectly can cause serious problems that may require you to reinstall Windows. Getting the Create a World tool to work with the Steam version of the game requires edits to the Windows registry. I’m going to preface this guide by saying that by far the simplest way to get the Create a World Tool working is to register your game on The Sims 3 website then download and install the game through Origin.
