I know that many guides exist for installing Battle.net onto the Steam Deck but I must have looked at about 30 different posts and videos on YouTube and have tried it several times myself and I always seem to run into the same problem. I have also tried this with a couple of different Proton versions including GE.

Every guide I have seen mentions adding the Setup exe as a non-Steam game, installing it, and then removing it and adding the Battle.net launcher to steam as a non-steam game.

If I do that the launcher disappears from my Deck and I am unable to launch it. I can’t find it with the Steam compdata folder.

So, what I tried was adding the Battle.net launcher as a non-Steam game and leaving the Setup exe in Steam and a non-Steam game.

When I do that I am able to launch the Battle.net launcher and login in fine to Battle.net. That’s when I run into my second issue. The launcher tells me that it needs to restart to update, but if never updates. It’ll either never close or it will restart but the update is not applied and the launcher tells me to restart to apply the update and the cycle continues.

Any advice or hints at what I am doing wrong are greatly appreciated.
