uplay needs to be installed from protontricks
-offline
I have removed prefix data from steam directories and replaced it with symlink to base HoMM7 prefix directory as described in a post under the link:
https://steamcommunity.com/app/221410/discussions/0/1642043732655737376/#c1642043732656904737
Launching with steam without tinkering would require another uplay installation. And first of all -> it would be separated from base HoMM7 instance.
- Install protontricks from flathub
- Install uplay into game's prefix
flatpak run com.github.Matoking.protontricks 445310 uplay
Sometimes uplay update on initial boot can get stuck, just restart until it updates properly and you'll be golden.
Installed uplay using protontricks
The game will not close (on Steam) after you quit to desktop
After the game installation you must install the Uplay separately with protontricks.
"protontricks 445310 uplay"
No more Uplay crashing and the game will work very well!
stuck at Uplay PC
Window appears "Unable to locate UplayPC. Please reinstall Uplay PC."
