From download to playing

  1. Run the installer

    On Windows, run the .exe; on macOS, open the .dmg and drag the app into Applications; on Linux, make the AppImage executable and start it.

  2. Sign in with Microsoft

    Sign-in opens in your browser, on Microsoft’s own page. The launcher never sees your password.

  3. Press Play

    On the Nether Client instance. The launcher installs Java, the game and the mods, then starts it.

Windows will warn you the first time

The Windows installer is not code-signed yet. When you run it, Microsoft Defender SmartScreen shows a window titled “Windows protected your PC” because it does not know the publisher. Choose More info, then Run anyway.

The installer sets up Nether Launcher for your Windows user only, so it does not ask for administrator rights. To check that the file is the one we published, compare its hash with the SHA-256 above. In PowerShell, in your Downloads folder:

Get-FileHash .\NetherLauncher-0.1.24-windows-amd64-setup.exe -Algorithm SHA256

Running the Linux AppImage

Make the file executable, then start it. To check it first, compare its hash with the SHA-256 above.

sha256sum NetherLauncher-0.1.24-x86_64.AppImage chmod +x NetherLauncher-0.1.24-x86_64.AppImage ./NetherLauncher-0.1.24-x86_64.AppImage

How updates work

Nether Launcher checks for updates when it starts and every 15 minutes while it is open. It updates itself, Nether Client and the managed mods, and checks every file against its SHA-256 hash before using it. You never reinstall anything by hand.
