The Witcher 3 install script, manual install not working

Hi, I’ve also posted about this on /r/linux_gaming and /r/linuxquestions

I’m trying to use the install scripts for The Witcher 3. I have the GOTY version but I’ve tried both scripts, and they just complain that they can’t authenticate with GOG. I already have the game installer downloaded, so why won’t they let me use it? I tried changing the script so instead of saying N/A:Select the game's setup file it just points to the file, but it didn’t make any difference.

I’ve also tried installing the game manually through Lutris, following along with the install script for as much as I understand it. The installer runs, at least, but the game crashes on startup.

The stickied post says to provide some logs, but I’m only allowed two hyperlinks??

I’m in the same boat…downloaded GoG W3 GOTY files (over slow internet connection) and trying to figure out how to install from local disk using lutris script…
