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, we decided with an opponent to continue a 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 with different mod versions, and they all crashed.

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 GameRiven after the tournament game failed. When I launched the game, the antivirus blocked it. The third version doesn't launch at all.

After that, I reinstalled the mod on one of the games, and it works through Hamachi, but not through GameRiven. It doesn't allow me to specify the game path in the options. Please advise what to do.

When I enter the path in the options and select any of the game versions, it says: "Select the game application for 'Heroes... 3'."
