Common Problems

We're having trouble starting Blizzard services. Please try again. If the problem persists, try restarting your computer.
Error Code: BLZBNTBTS0000005D

This error occurs when the Blizzard Update Agent is prevented from launching properly. This is usually caused by missing or corrupted Agent files. Follow the steps below to resolve the issue.

  1. Restart your computer to resolve problems caused by programs and services running in the background.
  2. Uninstalling and reinstalling the desktop app may resolve rare launcher issues.
  3. Update or temporarily uninstall any security programs, which may mistakenly identify the login module as a security threat.
  4. Try creating a new administrator account to resolve permissions issues.
