As topic says, how do I fix this? I google it at first, and seemed to find some guide that had me copying a file or two from game.gog into the data folder and renaming and editing dosboxDK.conf. Mainly because in the last step the line in the conf file I need to edit doesn't exist. I'm talking about a thread here on GOG, but I can't post a link it seems.

I think its a problem on gog's side. I have a previous instaler 2.0.0.4 wich has the deeper dungeon levels working fine. So the latest installer bugged something wich they should eventually fix.

Ahh okay I see. I hope so, thank you :)

I am also running it through galaxy, maybe that has something to do with it as well. Although I can't imagine the installers would be different.

I have the same problem and was just going to post a new thread about it. I hope they fix it soon.

I have yet to be able to run Deeper Dungeons since I started using Gog. I hope they fix this soon.

Just drop in to say I also have the same problem. Hope GOG can fix them soon.
Although $2.4 for Dungeon Keeper alone is already a sweet deal.

Don't bother with the Support. All they would tell you is run as admin, reinstall with standalone installer, or adding DK to antivirus/firewall exception list etc. general guidance which leads to nowhere.

Install KeeperFX. Problem solved.

Or, reinstall the game using the latest version (gog-7) wich has the issue already fixed.
