Go to unity3d.com and go to "UNITY" link at the top. From there, go to "Download" right under the main links at the top. After this, it will ask you which type of computer to download the free content for. Click on the one that is right for your computer (beware, the computer must be up to date and have a strong enough graphics card, and enough GB).
