This error occurs when the Blizzard Update Agent can't start due to missing or corrupted data. The Blizzard Update Agent is the program that launches, updates, and installs your Blizzard games.

  1. Delete the Battle.net Tools folder to automatically rebuild outdated or corrupt files.
  2. Update Flash in Internet Explorer, even if you normally use a different browser.
  3. Make sure Windows Secondary Logon is enabled, which Blizzard Agent requires to run correctly.
  4. Close all other applications to resolve software conflicts and free up resources.
  5. Disable or temporarily uninstall any security programs, which may mistakenly identify the login module as a security threat.
  6. If the problem persists, uninstall and reinstall the game.
