I bought the game, and I see it in my games catalogue, but the "Intall" button is greyed out.

I have Win 11 64-bit
All other games install OK

Im having the same issue, not sure what to tell you. Im still on windows 10 so I doubt its a windows issue. Trying to contact support.

So I exited GoG and the game finally showed up and let me install. If you have tried that then I officially dont know what to tell you.

I tried both:
- Log out/in Gog client - nope
- Kill Gog client, restart it - nope

Guess I'll contact Gog support

If it is the same issue I was having, the game wouldnt even show up in your library, no extras button to click, no way to get to instal, going to the store would tell you it was in your library and you could click Go to my library where it would show it in your collection but you couldnt do anything when you clicked on it. We have 2 different windows versions so I wonder if that might be contributing.

You should be able to download the game installer via the GOG website as well.

I don't even get that I get this:

"error": "invalid_licence",
"error_description": "User #46988899450094833 does not have the license for product #1584652180."
