Good detailed instructions, got it working on my Windows 10 Pro 64 bit system pretty much first go thanks. I installed it under a "regular" (not admin) user (but I had to be Admin to do the registry edit).
Couple of weird things I could use help with:
When I run the game it changes my Windows colour scheme to green, anyone got any idea why?
The Error messages in the registry entry for missing/wrong etc DVD seem to be irrelevant. If I run it without the DVD or with a random DVD in the drive, the error messages from the game are not those from the registry entry.
