Yeah, Dark Room has a complicated (unorganized) installation. Dark Room was built around the retail, non-Steam version of the game. So, in your case, you're going to have to dive into the archive and manually extract all folders with the name "darkroom" from the folders listed in the redist folder into their matching places of the Steam version of Amnesia. In other words, redist/billboards/darkroom goes into <Steam>/<Amnesia>/billboards/, redist/entities/darkroom goes into <Steam>/<Amnesia>/entities/, etc...
