Does anyone have any idea where the rights for Daedalus Encounter lie? (NB: it's in the wishlist.) Published by Virgin Interactive, who was purchased by Titus Software [according Wikipedia] who dissolved in 2005-2009, with no mention of any sale of their rights.

Issues might be technical rather than commercial as Moby
games lists it as a Windows 3.x game

Windows 3.1 games are 16bit windows only and are therefore pretty much irrevocably broken running native on 64bit Windows and there's nothing that could emulate them without breaching Microsoft copyright
Most win3.1 games also had a DOS version which will run in DOSbox but Mobygames, at least, seems to indicate that this isn't the case here, sadly!

It could be hard or very easy.

A lot of those FMV games were created using Macromedia Director (Daedalus Encounter being is one of them), so if the right owner still has access to the original assets and script its normally relatively easy to convert it to a more recent version of Director running on modern system.

Of course if the right owner doesn't have any of those then that's when the "hard" part kicks in...
