HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Hello! I bought the Complete edition on GOG. I installed it, applied the HD mod, and set all the settings to default. The menu is in English, and the game is also in English. How do I enable Russian language support? I thought that by downloading the HD mod in Russian, the game would automatically switch to Russian, but it seems there is no Russian translation in the HD mod...
