Failed to run a required program. Please wait one minute and try again. If this error reoccurs, please restart your computer and try again.

This error occurs when the Blizzard Setup program cannot run after an update. This is usually caused by another application preventing the Setup program from making changes to the game files on your computer. Follow the steps below to resolve the issue.

  1. Restart your computer to clear its memory and free up system resources so Blizzard Setup can run properly.
  2. Our games require an up-to-date operating system in order to run properly. Update your operating system and drivers to be sure you're using the most recent versions.
  3. Our games require administrator privileges to install, update, and run properly. Be sure to run the game in Administrator Mode.
  4. Programs running in the background can interfere with Blizzard Setup. Try closing background applications.
