Step-by-step installation and configuration.

Hello! I want to play Heroes 3. But I can't figure out what and how to install, there are many links on the internet, but I don't understand which one is needed. What I want is to have the following campaigns: The Restoration of Erathia, Armageddon's Blade, The Shadow of Death. HD mod. The ability to play SOD online (I heard that the Hamachi program is needed). All in Russian. For example, I downloaded the SOD, Complete + HD mod file in Russian from the hiros3.tv website, but there are some scripts written in it, as far as I understand, and I would like everything to be from scratch, without any settings. Could you guide me step by step through the installation and configuration of this game?!
