Getting the launcher on your PC, how updates arrive (small and automatic), and how to repair or remove it.

The first thing a new install shows: sign in with Microsoft, then a few quick steps (updates, terms, your public profile, importing from another client).

Installing

  1. Get SourClient-Setup.exe from the download page. sourclient.com is the only official source.
  2. Run it. If Windows shows Windows protected your PC, press More info and then Run anyway (why).
  3. The install takes a few seconds and puts Sour Client in your Start menu and on your desktop. It brings its own Java, so there is nothing else to install.

Minimum: Windows 10 64-bit, 4 GB RAM, a GPU around a GeForce GTX 745 / Radeon R7 240 / Intel HD 4400, and 2 GB free. Recommended: 8 GB RAM, a GTX 1660 / RX 580 class GPU and an SSD. The download page has the full table.

Updates

  • With Auto-update launcher on (Settings, Sour Client), new launcher builds install when you start it. A card says Build X is ready and the updater window shows its progress.
  • Updates only download the files that changed, so most are a few tens of megabytes rather than the whole installer.
  • Check for updates at the top of Settings checks right now. The build you are on is shown beside it.
  • Auto-update installed versions keeps game versions and Fabric current.
An update never starts while a game is launching or running.

Repairing and uninstalling

The install folder (normally C:\Program Files\SourClient) has two shortcuts: Repair SourClient, which puts back any missing or damaged launcher files, and Uninstall SourClient. You can also uninstall from Windows Settings, Apps. Uninstalling the launcher does not delete your game folders, worlds or screenshots, which live in your data folder (where your files are).
