Hi all!
Bit of a noob question post, I’m having some troubles moving my existing Battle.net prefix from Lutris to Heroic. I’ll walk through everything that may or may not be relevant below:I currently have Lutris installed via Flatpak:
And my battle.net prefix at this location:
Heroic I have installed via the .deb on GitHub - Version 2.20.1
In Heroic, I added a new game, selected the existing prefix location, and selected the Battle.net Launcher.exe (just copied what was already setup in Lutris), and selected GE-Proton10-33:
Now when I try to launch Battle.net through Heroic, the status will change from Launching to Playing, and I do see the Battle.net icon flicker into existence for a split second on my task bar, however Battle.net client doesn’t actually launch.
For reference also, I’m currently using Ubuntu 25.10.
Any advice on this issue would be greatly appreciated! Thank you!
I doubt that copying Battle.net over will work, I would try installing it via Heroic or Bottles, which has the installer preconfigured.
No reason why it shouldn’t work. I do stuff like this all the time.
And it does work, the problem was missing 32bit Vulkan drivers. I guess in Lutris Flatpak they are included, but I needed them actually installed for Heroic as I installed that via .deb.
I’m kind of struggling to understand why though? I’m just pointing at the pre-existing and using the same Proton version. What’s breaking here?
Have you tried running Heroic from the terminal? Do you get any error messages?
Yeah should have tried this from the start. Turned out the issue was just missing 32bit vulkan drivers, I guess those dependencies are included when running Lutris as a Flatpak, but with Heroic installed as a .deb I needed them to be system installed.
Anyway, problem solved, can happily play WoW again 😀
