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.
Error Codes: BLZBNTBTS0000005C, BLZBNTBTS00007

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

  1. Delete the Tools folder to have the Update Agent automatically re-create necessary files.
  2. Update or reinstall Adobe Flash Player.
  3. Make sure Windows' Secondary Logon is enabled, which the Update Agent requires in order to run correctly.
  4. Programs running in the background can conflict with the Update Agent. Try closing background applications.
  5. Security software can interfere with the Update Agent and prevent it from running properly. Disable or temporarily uninstall any security programs.
  6. If the issue persists, uninstall the game and download a new copy of the game installer from the Game Downloads page.
