Common Problems

Failed to run a required program (Agent). Please wait one minute and try again. If this error reoccurs, please restart your computer and try again.

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

  1. Delete the Tools folder to automatically rebuild outdated or corrupt files.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. Update 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.
