Can't install W40K Rogue Trader dlcs (GOG Version)

Hi,
I tried installing the dlcs i have since the game installation didn’t include those.
Once the setup is dowloaded here the window that is displayed:


As you can see i can’t check the box nor click the button.
Here is the issue report, the logs.
Thanks in advance for your help

& the console logs.

Not too sure how you’re installing the DLC, but I get the impression that you’re installing the DLC manually using the “Install a windows game from an Executable”

The way I install DLC is the instal the base game first, and then right click the game and select “Install DLCs”

If you are doing that, I have no idea as I don’t have Rogue Trader.

I do have the base game already installed

So manage to install:
It seems it was a Wine problem: could not install dlcs with versions 11.0, 11.8 & 11.12

Interesting. I’ve heard of issues with Proton 11, I stick with Wine-GE-8-26 for installations and the bulk of games, whilst sometimes I need CachyOS-Proton for a handful of a games for better compatibility.
