EDIT: The issue was caused by my SSD being formatted in exFAT, which doesn't support symlinks. I backed up my SSD & reformatted it to btrfs, and then I could install .NET without hassle & the game runs!
Original Post:
I'm having an issue running this game on linux, every time I click play in Steam I get the following popup:
"you must install .NET desktop runtime to run this application"
Clicking "yes" takes me to download a Windows .exe which of course can't run on linux. I manually installed the .NET runtime following linux instructions here: https://learn.microsoft.com/en-us/dotnet/core/install/linux-debian but the game still gives me this error.
Other things I've tried:
- Reinstalling BG3
- Completely deleting every file from steamapps/common for BG3 & reinstalling
- Reinstalling Proton
- Skipping the launcher
- Tried with proton experimental, 9, 8, 7
My launch args are STEAM_COMPAT_DATA_PATH=/home/user/.local/share/Steam/steamapps/compatdata gamemoderun %command% --skip-launcher
On protondb everybody else seems to be running the game fine, but I don't understand how to get past this error.
Skip the useless launcher. Set the steam shortcut to run the game exe directly, it doesn’t need anything special, been playing it fine on Debian and arch with both nvidia and amd gpus as well as my steam deck.
I already skip the launcher but this error still happens. My launch args are
STEAM_COMPAT_DATA_PATH=/home/user/.local/share/Steam/steamapps/compatdata %command% --skip-launcherDid you try stripping out everything in the launch options except ‘--skip-launcher’? I tried your command and it didn’t launch but then tried just the skip option and it worked again.
I need STEAM_COMPAT_DATA_PATH because my proton is installed in a different steam library than the game, all of my proton games use this. I tried to remove it anyway and try just '--skip-launcher', but now the game doesn't launch lol
The command likely won't work for you because you don't have proton installed at that location
