Battle.net® Desktop Application

Keywords:

The Battle.net® desktop app improves patching and installation and makes login quick and easy with a single sign-on feature. The app handles installing World of Warcraft®, StarCraft® II, Diablo® III, and Hearthstone™ from one central location and it updates your games when a patch is available. You can also use the app’s game pages to stay on top of the latest Blizzard news.

The Battle.net app replaces our previous game launchers. Eventually, all game launchers will be upgraded to the Battle.net desktop app. The app will also act as your gateway to future Blizzard games.

Single Sign-on

You’ll log in to the app using your Battle.net account information, so it will log you in to all your Blizzard games—you’ll never have to enter your username and password on the game screen again.

If you have Keep me logged in enabled (in Settings > General), the app will keep you logged in for up to 30 days. During those 30 days, you’ll log in automatically if you exit and restart the app.

Note: You can log in to the Battle.net desktop app on multiple computers. The original login will expire if your account is logged in from another computer.

Installation and Patching

As long as the app is running, it will download and install available patches in the background. The app will only patch one game at a time, and you can manually pause or continue patching in the app. You can also disable auto-patching in the app’s Options menu.

Troubleshooting

Check the Known Issues List or visit the Battle.net Technical Support forums to see if your issue is mentioned there.

World of Warcraft and StarCraft II players can switch to the previous launcher by uninstalling Battle.net. As long as Battle.net is installed on your system, you will not be able to access World of Warcraft or StarCraft II through the old launchers. Battle.net is required for Diablo III players.
