The Launcher Closes Without an Error After Pressing Play


This issue is most common after a patch. It is typically caused by the launcher or Desktop application patching incorrectly. To ensure the application can update correctly, follow the steps below:

  1. Run the launcher in Administrator Mode to address many installation, patching, networking, and start-up errors.
  2. Ensure your operating system, network card, and video card drivers are up-to-date.
  3. Security software may interfere with the launcher. Disable or temporarily uninstall any security programs.

If you have tried all of the steps for your operating system and still require assistance, please visit our Technical Support Forum (World of Warcraft) (StarCraft II) (Diablo III) (Hearthstone) or contact us.
