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

Good afternoon. If I remember correctly, on April 19, 2013, my opponent and I decided to continue our tournament game. When I tried to enter the game, my antivirus immediately blocked a malicious file and provided a link to the HD mod. I clicked "unblock," but the mod had already disappeared from the game folder. I have three versions of the game on my desktop, each with different mod versions, and they all crashed. Added 2 minutes later: The first one crashed when I tried to play a tournament game through Hamachi. The second one – I decided to play a casual game on GameRanger after the tournament game failed. When I launched the game, the antivirus blocked it. The third version doesn't launch at all. Added 2 minutes later: After that, I reinstalled the mod on one of the games, and it works through Hamachi, but not through GameRanger. It doesn't allow me to specify the game path in the options. Please advise what to do. Added 8 minutes later: When I enter the path in the options and select any of the game versions, it says: "Select the game application for 'Heroes... 3'."
