Heoes 3 - A tribute to Warcraft

It should be installed on SoD, that's the only way.

I did that, but I get an error when loading. I tried different versions, several English ones. But when I start installing the DOMM file, it gives an error.

If anyone has installed it, please describe how you did it and which version of SoD you installed it on.
Maybe someone wouldn't mind sharing an SoD with the mod already installed?
