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.
Have you tried (in Steam’s properties for the game) switching the compatibility setting to force Proton Experimental? You might also need other workarounds, like configuring Steam to skip the game’s launcher.

Thank you, Yes experimental is the one I tried as per people’s recommendation on protondb. I have also tried 9, 8, 7 but all give the same error. Putting the --skip-launcher argument in still brings me this error. I can’t even get to the launcher 😭
