Hi b3nn0,

hope you're still hanging around. I'm pretty new to Linux (Fedora 43 distro) and tried to install SkyDemon via your Lutris installation script.

The install process itself seemed to work well (except I was asked a gazillion times if I want to install Dotnet 4.8.1), but I ran into two problems after the installation was finished.

1.) SkyDemon.exe could not be found. Reason: path is set to "/home/[username]/Spiele/skydemon/drive_c/Program Files/SkyDemon/SkyDemon.exe", but my version of SkyDemon (I installed V4.2.3) installs the exe into "/home/stephan/Spiele/skydemon/drive_c/Program Files (x86)/SkyDemon/". I set the new path manually in the SkyDemon settings under Lutris. 

2.) After solving problem 1, I was greeted with "Proton is not compatible with 32-bit prefixes."

I'm wondering if an Linux, Wine or Proton update messed up your script or if I'm just making a mistake during the installation process.

Here is the detailed log:

Proton is not compatible with 32-bit prefixes.

If anyone else installed SkyDemon lately under Linux, I would appreciate any help since I tried several different ways to get it running, but to no avail.

I recently managed to get it working under debian trixie with the standard wine-stable from this distribution (version 11.0.0.0~trixie-1) without any additional software like proton. To install the reqired dotnet versions I used winetricks (version 20250102-next). My winetricks-log for that looks like this:
winxp
dotnet40
dotnet45
dotnet46
dotnet461
dotnet462
dotnet472

If anyone is interested: I created an installer-script for Lutris, which will install all needed dependencies. It will also configure wine to use a virtual desktop, otherwise the mouse-hover popups will not work. If you don't like it, feel free to disable that.

+x

I recently got it running with wine under Gentoo Linux. For setting it up I used the tool Q4wine, with actually does all the winetricks stuff and furthermore creating a new enviroment. Make sure that is is 32bit! I run the dotnet 4,72 winetricks scripts and it finally worked. There is one feature missing: If you move the curser over certain airspaces, it does not show up a tooltip like window which explains the airspace structure at that point. This is not a big issue because you can see it on the virtual radar as well or you just need to check the bounderies on the map.

But I did not discover any other flaws, it is completly useable. If you stress the application window: Resize, fullscreen, toggle window mode and something like that a crash might happen. I got it twice in the last weeks but when do normal planning stuff it looks stable. I will keep on running it in wine because using a VM for it is just a overkill and the wine version is much faster. It is incredible fast compared to Virtualbox. Just ask if you have futher questions.

I like it on linux (mint) too. But I'm struggling with linux basics.
How do you add the dotnet 4.72 exactly? I found it in the Menu "Settings" -> Winetricks -> dlls. I was able to click and install it. But when I start the skydemonsetup.exe in the explorer, I get the error "SkyDemon requires Microsoft .NET Framework 4.7.2"
What is missing?

EDIT: Note however, that I did try to install a bunch of things to get the previous version running (without success). Not sure if it would also work without this.

We don't support Linux, but have no problem with people setting up an emulation environment to run SkyDemon under such conditions.
