Launcher Won't Open

A blank window, a launcher that does nothing when you open it, or one that freezes.

Launcher
  1. It may already be open. If On game launch is set to Hide to system tray, the launcher is in the tray by the clock. Click its icon there.
  2. Close it fully: right-click the tray icon and quit, or end every SourClient process in Task Manager. Then open it again.
  3. Update your graphics drivers. The launcher draws with your GPU; a broken driver can leave the window blank.
  4. Repair it. Run Repair SourClient from the install folder (normally C:\Program Files\SourClient). It puts back missing or damaged launcher files.
  5. Reinstall. Download the installer again from sourclient.com and run it over the top. Your profiles, worlds and settings are kept.
Launcher logs are in %USERPROFILE%\SourClientData\logs. Attach launcher.log to a ticket if it still will not open.
