Installing it on Linux

[Shepiwot]

I use Steam for its Proton layer; I find it makes things simple.
1) Add the launcher as a non-steam game
2) right click, properties
3) Force compatibility and select Proton 9
4) Launch

How did you get the launcher's exe to add to steam?
I'm trying to get things to work on a steam deck for travel abroad but to get the launcher, I have to make use of its installer, but if I install the launcher using lutris or steam, afaik it only exists in an emulated space from which I cannot actually access and add it to my steam library?

Did you manage to run it on Steam Deck successfully?

Any update with the steam deck? Going to try and mess around with it tomorrow but I was able to get game files download and able to play. But never figured out how to get launcher to work properly to be able to update with how having to reinstall all game files over again.

Plus with the launch i can use auto loot which is about 90% of why i want to be able to play or atleast update thru the launcher.

Hello!

About the launcher unable to update itself or always applying the same patch over to the game, the trick is to use the "STEAM_COMPAT_DATA_PATH" environment variable in the launch options of Steam for the launcher .exe file you added as a non-Steam game.

This environment variable is used to change the Proton "prefix" to use.
Steam created a prefix when you ran the launcher's installer using Proton, and installed the launcher in this prefix. If you then add the launcher the same way in Steam, it will create a new prefix for that "game" when you run it as well.

I will roughly describe the steps to install the game correctly on Linux, using Steam. Read it thoroughly before doing anything, as understanding these principles will help you in the long run using Linux You will then be able to troubleshoot pretty easily.

* Run the launcher's installer using Steam, DO NOT RUN THE LAUNCHER DIRECTLY AFTER
* Find the launcher's location using the following command from a terminal

Code: Select all

find ~/.steam/steam/steamapps/compatdata/ -name "OctoLauncher.exe"

The result will look like

Code: Select all

/home/linuxuser/.steam/steam/steamapps/compatdata/2669118820/pfx/drive_c/users/steamuser/AppData/Local/Programs/OctoLauncher/OctoLauncher.exe

Note that the first part is your prefix:

Code: Select all

/home/linuxuser/.steam/steam/steamapps/compatdata/2669118820

* Use the full address to add OctoLauncher.exe to Steam, as a non-Steam game (do not run it yet)
* Change the launch options of the newly added game in Steam (right click > properties > launch options) to the following (of course, you will have to replace with the prefix you found earlier):

Code: Select all

STEAM_COMPAT_DATA_PATH="/home/linuxuser/.steam/steam/steamapps/compatdata/2669118820"

Don't forget to select some version of Proton in the "Compatibility" section of the game in Steam. You can now run the launcher from Steam and the issue should be resolved.

Of course, if you have already set up most of this and got the game running, but only want to fix the launcher issue, you can simply update the launch options to use the right prefix.

I hope this helps!
