Notice: All the players have to setup the HoMM 3 in the same way. If someone hasn’t installed HD mod, they cannot join to HD game. If all the other players have untouched GOG version of HoMM3, but you have the HD mod installed, you cannot join to game. Remember that you have the original untouched executable, so if you need to play the original version without mod, you just rename the Heroes3_backup.exe as Heroes3.exe.
