I need Heroes of Might and Magic III version 4.0.

Here's what I found. The game's language is English when launched with GRa, version 4.0. The only thing I did was rename the Heroes3 file that was in the archive when I downloaded Heroes from the website; its previous name was Heroes31, but the connection problem remained. What did I do wrong? I tried creating an executable from HD Launcher, but the executable version was 3.2. After that, I simply tried renaming the existing file, and the version became 4.0.

Another surprising fact: the standalone SOD version on my computer, version 3.1, connects to an opponent but displays a message saying that the versions are different; the host has version 4.0, and I have version 3.1. With my 4.0 version, nothing is known.
