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.
I’ve never been able to get a launcher to work on Linux and it’s frustrating. Gonna give Bazzite a try soon though. Best of luck OP, I feel your pain.
