Common Problems

Whoops! Looks like something broke or crashed. Please try restarting the app. If that doesn't work, try restarting your computer. Agent Went to Sleep

The desktop app failed to communicate with the Update Agent, which is required to install, update, launch, and uninstall Blizzard games.

  1. Update your drivers and operating system to resolve any compatibility issues.
  2. Run a security scan to remove any viruses or malware infections.
  3. Update or temporarily uninstall any security programs, which may mistakenly identify the login module as a security threat.
  4. Create a new administrator account to resolve permissions issues.
  5. Uninstalling and reinstalling the App may resolve rare launcher issues.
