Common Problems

Failed to launch Agent or AgentSwitcher. Please close all other applications, temporarily deactivate your anti-virus software, and try again. Alternatively, log in as an administrator and try again.

The Battle.net desktop app can't launch the Battle.net Agent or AgentSwitcher, which are required to install, update, and run Blizzard games. Permission conflicts or file corruption can cause this error to display.

  1. Restart your computer to resolve problems caused by programs and services running in the background.
  2. Uninstalling and reinstalling the Battle.net App may resolve rare launcher issues.
  3. Update your drivers and operating system to resolve any compatibility issues.
  4. Try creating a new administrator account to resolve permissions issues.
  5. Configure your security software's exception list to allow Blizzard applications to run.
