Unity download archive
From this page you can download the previous versions of Unity for both Unity Personal and Pro (if you have a Pro license, enter in your key when prompted after installation). Please note that we don’t support downgrading a project to an older editor version. However, you can import projects into a new editor version. We advise you to back up your project before converting and check the console log for any errors or warnings after importing.
