  1. 1

    Download

    The button above saves SourClient-Setup.exe to your Downloads folder.

  2. 2

    Run the Installer

    A blue “Windows protected your PC” box is normal for a new installer. Click More info, then Run anyway. Check the file yourself

  3. 3

    Sign In

    Use the Microsoft account that owns Minecraft: Java Edition. You sign in on Microsoft’s own page, so your password never reaches Sour Client.
