Common Problems

  • Getting the BLZBNTBTS0000005C error

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. Restart your computer to resolve problems caused by programs and services running in the background.
  2. Delete the Tools folder to automatically rebuild outdated or corrupt files.
  3. Try creating a new administrator account to resolve permissions issues.
  4. Close all other applications to resolve software conflicts and free up resources.
  5. Uninstalling and reinstalling the App may resolve rare launcher issues.
