Windows 10 and Heroes 3 – anyone know how to make it work? Help!

heroes3.tv - register on this website, and you'll be happy. The "DOWNLOAD" section. Everything there works, and there's a lot of interesting stuff in general.

That's where I downloaded it from =)
Here it is:
Clean Heroes 3 Complete ENG (860 MB) - a collection of all three official parts of the Heroes of Might and Magic 3 game, without pre-installed mods, in English. After downloading, you can decide for yourself which mods you need for this game.

But there are errors related to libraries that cause crashes.
