The desktop app is a very useful tool for gamers, allowing them to install and patch Blizzard games  faster. Thanks to this app, all your games are in one place, you only need to log in once, and all game updates are downloaded automatically.

The desktop app relies on a process called Agent to install and patch Blizzard games. In case Agent can’t download data or install game files, follow the troubleshooting steps listed below to fix this problem.

Fix install and patching bugs

  1. Restart your computer. This simple action allows you to close the Agent process and lets the desktop app update it.
  2. Use a wired connection. Wired connections are more stable than wireless connections. When using wireless connections, the dropped data packets can slow down the install or update process and even cause various errors.
  3. Disable or temporarily remove your security software. Sometimes, your antivirus may prevent you from downloading new files.
  4. Make sure you’ve installed the latest updates available for your operating system.
  5. Make sure the Windows Secondary Logon service is enabled for Agent to run.
  6. Run a full system scan to detect potential malware infections. Malicious programs may interfere with the Agent.
  7. Disable specific add-ons for particular games. For example, World of Warcraft addon managers can prevent Agent from updating game files. Disable the addons, restart your computer, and try again.
  8. Agent files may be corrupted from a previous installation attempt. For this reason, delete the Tools folder and open the desktop app again to download a new Agent version.
  9. Temporarily disable your proxy settings.
  10. Make sure both your internet browser and Adobe Flash Player are up to date. Running outdated versions of these tools can prevent Agent’s from connecting.
  11. Manually update the Agent.
  12. If the steps listed above didn’t help you, uninstall and reinstall the game.
