For those of you who try to launch the game and receive an error message asking you to install .Net Framework 4.7.2 but are not able to install it due to another error (typically error "hresult 0x800f081e") here is the simple workaround :)

Since the problem is with the damned launcher as with many new games, you just need to skip it. The way to do it is go to your folder:

C:\GOG Games\MuHa Master of Magic

And launch game with the file "MoM" as shown on the attached image...

Enjoy! ^^
