That's exactly the link I already provided ;)

Here's a quick 'how-to' on installing the remaster from GoG. Please note that I'm using an up-to-date install of 64bit Manjaro (Arch) and already have installed both wine and winetricks.

When downloading, do *not* hit the big blue "Download and install now" button. That's for GoG Galaxy which we don't want. Instead, near the bottom of the download box use the link for the Trilogy in the 'offline backup game installers' section.

It should be called something like setup_the_bards_tale_trilogy_1.00_(#####).exe (where # is a 5-digit number).

From here, it was easiest for me to finish via command line, as well as put the game in it's own section(or wine 'bottle') :

WINEPREFIX="/home/YOURUSERNAME/.wine-btr" wine /path/to/setup_the_bards_tale_trilogy_1.00_\(12345\).exe

This will start the installer - just complete it as normal. NOTE : for me, it threw several errors at the end, but that didn't seem to actually affect the install.

Next, install the Vulkan compatibility bit
WINEPREFIX="/home/YOURUSERNAME/.wine-btr" winetricks dxvk

From there I had a desktop shortcut and menu item to start it from. Alternatively, you could start it with :
WINEPREFIX="/home/brose/.wine-btr" wine .wine-btr/drive_c/GOG\ Games/The\ Bard\'s\ Tale\ Trilogy/TheBardsTaleTrilogy.exe

Beemer

It's also recommended to enable virtual desktop in Wine for it. Otherwise it gets messed up if game window will lose focus.

Thanks to all of you for this excellent information.

Managed to install BT via Lutris and updated wine-prefixes.

WINEPREFIX="/home/YOURUSERNAME/.wine-btr" winetricks dxvk

After that simply activated "dxvk" in the runner's options.

Works like a charm now... many thanks to all posters and helpers.

Mangar! Watch out! I'm coming for you!!!

In case somebody comes to this thread before buying the game for his Linux-machine I wanted to update that since patch to version 1.09 it works for me out of the box.

I asked a dev on twitch(just around game launch) about if it's coming to linux and the response was "It will be up to brian fargo". It seems they're really trying to get the Bard's Tale 4 on Linux so with any luck or how well that goes we might end up getting a port. (don't hold your breath)

i just installed the game yesterday with playonlinux a new 64bit prefix plus dx11 and it's working well (except the first time i started it)
