Troubleshooting "Initializing..."


If the launcher remains on this splash screen for a long period of time, this indicates the launcher is having difficulties obtaining data to start up. 


  1. Programs running in the background can conflict with the Update Agent. Try closing background applications.
  2. Security software may interfere with the Update Agent. Disable or temporarily uninstall any security programs.
  3. You must have a stable internet connection to update and play our games. Try optimizing your internet connection.
  4. Windows Secondary Logon service must be enabled for the Update Agent to do its job. Ensure that the service is turned on.
Advanced Troubleshooting
  1. Ensure that your network is properly configured for Blizzard games and services.
  2. Some advanced internet settings may prevent the Update Agent from connecting to our servers. Check your Proxy and Work Offline settings.
  3. Make sure that both your internet browser and Adobe Flash Player are up-to-date. Both can affect the Update Agent's ability to properly connect.
  4. The Update Agent may be corrupted or damaged. Delete the Tools folder and the Agent will be downloaded again.


  1. Run the game on an Administrator account to resolve any user account permission conflicts. 
  2. Restart your computer to resolve any temporary OS issues that may interfere with the Blizzard Launcher. 
  3. Our games require an up-to-date operating system to run properly. Run Software Update to be sure you're using the most recent version.
  4. Reset game folder permissions to ensure the Blizzard Launcher is able to access game data required for startup.
  5. Programs running in the background can conflict with the Blizzard Launcher. Try closing background applications.
Advanced Troubleshooting
  1. Repair Disk Permissions to resolve OS conflicts which may prevent the Blizzard Launcher from starting up. 
  2. Deleting the Tools folder, which contains Blizzard Launcher and Update Agent data, can resolve this issue by forcing Update Agent to automatically create files again when it restarts.
