Guide on adding a new model, animation, and creature to HoMMV

Find the user Esto100nec on the forum; there's a link to his disk with files in his signature; it will contain the "Archangel" program and, most likely, instructions on how to use it.

The program has already been downloaded, but nothing worked... But in general, is it even possible? I mean, can I extract the model and animation files?

To be honest, here's why I need it: I really want to create a mod for either Attila: Total War or Troy: Total War, specifically based on Heroes of Might and Magic 5. There are two options: the first is to extract everything from Heroes and implement it, and then enjoy the result... The second option is worse: to create everything from scratch, models and animations, insert them into the game, and again enjoy the result... But if I can manage the first option on my own, albeit slowly... Then the second option requires a team...
