Game starts from installation dialogue, doesn't want to use 64-bit-prefix afterwards (0.5.20)

[Skryer]

I wanted to check out the new runners after updating to 0.5.20; installed Ghost of a Tale as a test, and ran into a strange problem.

The game started perfectly fine after pressing the launch button on the installation dialogue directly after the installing the game, but if I want to run the game from my library, it somehow couldn’t create a 64-bit-prefix?

Here’s the error log:

Proton is not compatible with 32-bit prefixes.

I’m on vanilla arch and have reset all settings to default, if that helps.

There is a similar issue here:

Shadow fo Mordor from GOG does not launch, but launched after install

Hello I solved my own problem and wanted to share in case others ar searching. I installed the game from GOG and it launched at the end of the install process but would not launch from lutris. I was able to get it to launch from the Wine Console. So i decided to disable and remove everything in the config and re-enable options and got it to work. The issue was the argument “-english” in Game Options > Arguments. Removed that and now its all good.

…but I don’t think that this has the same cause.

Lutris now uses Proton by default and Proton does not support 32 bits wineprefix.
Solution:

• reinstall your game in a 64 bits wineprefix
• use a Wine version that supports win32 wineprefix, you can add others wine version to Lutris using ProtonPlus

Hello legluondunet!

Thank you for your quick reply and especially for the great work you are doing with creating and maintaining your install scripts! Always happy to see one.

I am not sure whether this is really an issue with the prefix though, but maybe I am missing something:

~ I was able to use Proton (Experimental) perfectly fine before the update to 0.5.20. In fact, I use Lutris mainly for Proton outside of Steam, and to manage source-ports or mods with install scripts.

~ The installation has supposedly created a 64bit-prefix specifically for the game (see: [INFO:2026-02-19 11:58:07,853:wine]: win64 Prefix created in /mnt/avalon/Spiele/gog/ghost-of-a-tale in the log), which is also present on my drive

~ Even if I create a new 64-bit-prefix directly in Lutris, it still throws the same error

I agree that it somehow can’t access the prefix, but I am pretty sure it is present. Switching from the newly introduced Proton-GE (very cool that Lutris now handles Proton-GE!) to different versions of Proton/Wine doesn’t seem to do the trick as well.

e: The Wine prefix setting on Configure → Game options also points at the folder where the log has supposedly created the prefix (/mnt/avalon/Spiele/gog/ghost-of-a-tale)

Quick update: I have checked the generated prefix by looking at the version file, and yeah, Lutris gave me a 32-bit-prefix.

It worked after using the “auto-generated” install option instead of the unmarked Wine install.

I still wonder what causes the default unmarked option to generate a 32-bit-prefix though, especially for a game from the late 2010s.
