The button is faded out for me: https://download.battle.net/en-us/desktop
But as soon as I change my user agent suddenly it works 🤔 However starting it with wine gives an error that it can’t connect to the server. No more blizzard games I guess
With a previously installed client I was able to buy and download Diablo II: Ressurected, but after starting it it immediately stated that my setup was to outdated to run this game. I highly doubt that, since I have more than the minimum requirements.
I found out that you have to fool the game to make it start: https://forums.lutris.net/t/solved-diablo-ii-resurrected-fails-to-start-with-failed-to-initialize-graphics-device-error/13878/3
Problem was with ingame GPU and driver version detection
The lutris battle.net installer however did not work, and I didn’t have the mood to debug it.
Not so surprising, but they don’t support linux: https://us.forums.blizzard.com/en/d2r/t/failed-to-initialize-graphics-device/5896/67
Note: Linux, bootcamp, or running the game in a virtual OS is not supported
I use Bottles launcher for things like Battle.net, works great, even has simple one click install for it. It’s available and maintained as flatpak.
Bottles was the only thing that’s ever worked for me with nonsteam games. Love it!
