If you do not receive an error code, the steps below may resolve problems in which the Battle.net Desktop Application can’t download data or update game files.
- Restart your computer to resolve problems caused by programs and services running in the background.
- If you're using a wireless connection, optimize your internet connection to rule out a connection issue.
- Delete the Battle.net Tools folder to automatically rebuild outdated or corrupt files.
- Update your drivers and operating system to resolve any compatibility issues.
- Make sure Windows Secondary Logon is enabled, which Blizzard Agent requires to run correctly.
- Run a security scan to remove any viruses or malware infections.
- Disable or temporarily uninstall any security programs, which may mistakenly identify the login module as a security threat.
- Disable any proxies that may interfere with the login module.
- Check your network configuration to find any issues with your firewall, router, or port settings.
- If the problem persists, uninstall and reinstall the game.
