There's no explanation anywhere.

There's a big button in the game that says "start download" all it does is it says lol you can't, use the client (not exactly helpful i guess they put it in there to piss of the buyers.).

it's not in Games since it's not a game.

It's nowhere to be found if i go to Cyberpunk.I went to "DLC", it's empty.

Thanks.

Edit: ok, so it seems like you must close down GOG entirely, restart it. Then it seems like it's
updating CP with the DLC. What tards... how hard can it be to make it install after you've purchased it,
and if not, then make that useless button say "please close down your client and restart it." then at least
it serves some kind of purpose.
