Just bought Witcher 3 - Wild Hunt, and was looking for the dlcs in gog galaxy, nowhere to be found, you have to actually go to your webpage, and buy the free DLC pack for 0.00USD, and the add it to your account. I then tried to download the 16 DLC pack multiple times with no luck, its not telling me why, and ive tried everything, even reinstalling/verifying the game. And still non of the 16 dlcs, that i just added to my account.

I'm impressed, really. Given that I've tried at multiple points to install CDE and are currently using the WIndowMaker desktop, I have my doubts that Galaxy 2.0 is really the worst user interface you've tried.


A thought occurs.

Have you tried manual style?

If you use Galaxy, open the installed tab (left side) then look for Witcher 3. Rightclick on it, then 'manage installation' > 'configure'. There the DLCs should be listed. Installed DLCs have a tick. Click on the unticked to install them.
