This is driving me crazy. I’m trying to run BG3 and I’m running into a variety of errors:

My step up:

OS: Ubuntu 22.04.3 LTSKERNEL: 6.2.0-26-generic CPU: AMD Ryzen 9 7950X3D 16-Core GPU: AMD Radeon RX 7900 XTX (gfx1100, LLVM 15.0.7, DRM 3.49, 6.2.0-26-generic) GPU DRIVER: 4.6 Mesa 23.3git2308230600.fbf3f6oibaf~j (git-fbf3f64 2023-08-23 jammy-oi RAM: 63 GB

One seems to be this for which I feel I’ve tried every googable solution:

You must install .NET to run this application.

App: Z:\home\peafield.local\share\Steam\steamapps\common\Baldurs Gate 3\Launche r\LariLauncher.exe Architecture: x64 App host version: 6.0.18 .NET location: Not found

Another is this:

ERROR: ld.so: object ‘/home/peafield/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so’ from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

But I’m not even sure what this points to now.

Can anyone help? Or is anyone going through something similar with a similar set up?

EDIT: The solution, as many of you suggested, was to just change distros. I’d heard good things about Fedora so I tried it and everything ran first time with no tweaking! Thank you everyone for the advice.

  • ProtonTricks may be the app for your problem. It can run Winetricks specifically targeting the prefixes that Steam sets up for each individual game. Soo, (I do not have BG3) run Protontricks, pick the game, wait, find that Winetricks starts off at a really awkward point in its UI, pick add an application, cancel, find yourself at a better menu, choose “Install a Windows DLL or component”, and check off the appropriate dot net version.
