Could you please provide more details? What exactly happens when you try to download the DLC? And what steps are you having trouble with?

I use the app of itch.io for mac since It wont let me download games directly off the website , so when i download the dlc and look into the files its just there with the other games i downloaded. i dont really know how to move it without copy and pasting it so thats what ive been doing to put in the game file for 14dwy, then when i open the game the dlc isnt there. The steps werent hard to follow though!! Im not sure if i'm doing it right though ^^ sorry if my explanation was bad, im happy to clarify anything else if needed
Unfortunately, I'm not really familiar with the Itch app since I don't use it, so I can't be much help ^^; Here's a comment thread with a similar issue to yours, but I'm not sure if it'll work. All I can suggest is downloading the base game and DLC manually.
