The HTML conversion link in the OP should really be updated or at least include the LD conversion.
Frank's LD mod usually has a pretty recent Regalia port.

So many people here seem to struggle to get Rags running and even if they manage a lot of people probably drop it because of the UI, which is a shame because once you grasp the mechanics, the game is pretty great.
While I appreciate the games Rags has enabled, it is terribly outdated at this point. I highly recommend playing the regalia version. Easy "install", native dark mode, font-size adjustments, tiny save files, and only slightly more buggy than the base game.
Just avoid using the cancel option when assigning people to jobs and you should be fine.
