Common Problems

  • Purchased StarCraft II but can't install it
  • Can't install Starcraft 2

Troubleshooting

  1. Restart your computer before doing any other troubleshooting. This can resolve many program conflicts and other temporary issues
  2. Optimize your internet connection. Your current setup may be preventing patching
  3. Configure your security software to allow our game to be installed or updated
  4. Uninstall and reinstall your Battle.net App
  5. Run the repair tool to repair any damaged game files
  6. If all of the above fails, try updating or creating a new Windows account to resolve permission issues with your operating system (Windows 10 and 11 only)
