This is an official fix for running Dinosaur Hunter, 3D Dino Worlds and other Dorling Kindersley games under Win XP.
Dorling Kindersley released this fix for their catalogue of educational games under the "Eyewitness" banner. Normally when installing the game under Windows XP it causes an issue complaining about sound. This fixes that immediately. This fix also works with 3D Dino Worlds (which is included in the 2.0/Deluxe edition of the game) and potentially with other Eyewitness games.
This fix used to be located on their support website which is no longer available. I only discovered this fix thanks to an Amazon review telling me the exe name and through digging through archive.org. Hopefully more people will experience this game now since it can run on Windows XP.
