This tutorial will show you how to install the Battle.net launcher on the Steam Deck.
The battle.net launcher is home to numerous games you may want to play on your Steam Deck. This includes hits such as Diablo 4, Starcraft and more.
Like with using Ubisoft Connect on your device, using Battle.net is not as straightforward as you would hope.
By the end of this tutorial, you should have the Battle.net client installed and running within Steam Deck’s gaming mode.
To make the setup of experience of Battle.net on your Steam Deck smoother, we recommend using a keyboard and/or mouse. However, it is fully installable using the Steam Deck’s controls and on-screen keyboard.
Using the Battle.net Launcher on the Steam Deck
Over the following sections, we will show you how to install and use the Battle.net launcher on the Steam Deck.

To do this, you will want to open your favourite web browser. In our screenshot below, we will be opening the Firefox browser.

Upon opening this web page, the client will automatically begin to be downloaded to your device.
Adding the Battle.net Installer to your Steam Deck Library

With the compatibility screen open, ensure the “

Finally, ensure that the version of Proton is set to “

Tap the “

Changing the Battle.net Launch Target
19. At this point the Battle.net launcher in our Steam Deck library is still pointed to the installer.
We must adjust this value before you can easily launch the client within gaming mode.
To do this, find the “
Battle.net-Setup.exe” entry in Steam and open the preferences by tapping the “

31. Next, change to the “
Program Files (x86)” folder. This is where we installed the Battle.net client.
32. Within this directory, find the one called “
Battle.net” and open it.
33. Finally, find the file called “
Battle.net Launcher.exe” and tap it.
With the option selected, tap the “
OPEN” button to select it as the launch target.
Updating the Battle.net Start In Target on the Steam Deck
34. If the “
START IN” textbox is still set to the default value, then you will need to update it. Steam typically will automatically set the correct value, but some releases break this behaviour. If it looks correct, skip to the next section.

Ensure Target and Start In has Double Quotes
46. Both the “
TARGET” and “
START IN” fields require there to be a double quote (
") at the beginning and end of the lines.
Make sure this double quote is there before proceeding. Steam is meant to automatically add this but this functionality it sometimes broken.
Adding a Directory to store Battle.net Games on the Steam Deck
47. To make storing your battle.net games on your Steam Deck easier, we will create a directory within your user’s home directory.
Once created, we will create a symbolic link between this folder and the simulated “
drive_c“folder within which the Battle.net client is running.
If you are happy for your games to be stored within the proton directory, you can safely skip to the next section. However, these will be deleted whenever you uninstall the Battle.net client.
To begin this process, return to the desktop and open the Dolphin file explorer. This explorer is represented by the folder icon in the task bar.

Finally, ensure that the sort by is set to “

Changing the Default Input Settings for Battle.net
