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.
The proton prefix should not be created on the external drive, but in the Steam folder in the home directory, I’m pretty sure. Even with a second Steam game install location. Why is it not there?
No, it is created when Wine initializes the prefix. It has absolutely nothing to do with .NET.
