Battle.net Agent Troubleshooting

Keywords:

Battle.net Agent is responsible for updating and launching your Blizzard games. If the Battle.net Agent is not working properly, you may encounter patch looping, an inactive Play button, or a patch getting stuck at Updating Setup Files. Follow the steps for your operating system below to resolve issues with the Battle.net Agent.

Windows

  1. The Battle.net Agent may not work with an outdated operating system. Update Windows.
  2. If you're using wireless internet, switch to a wired connection.
  3. Some advanced internet settings may prevent the Battle.net Agent from connecting to our servers. Temporarily disable your proxy settings.

  5. Programs running in the background can conflict with the Battle.net Agent. Try closing background applications.

Advanced Troubleshooting
