Debian stretch: 'wine: Install Mono for Windows to run .NET applications.'

[rodrigoSantamaria]

Hi there,
I followed the guide about installing wine and winetricks (not mono) and I think everything went fine, but I got that error:

$ wine --version
wine-5.0

$ winetricks --version
20191224 - sha256sum: bd028907054679ece1f958c0df39b54ef3dcd6e2e6842c03874e7f530406350f

$ WINEPREFIX=~/.wine-octgn wine '/home/rodri/.wine-octgn/drive_c/users/rodri/Local Settings/Application Data/Programs/OCTGN/OCTGN.exe'
wine: Install Mono for Windows to run .NET applications.

I think this line did not install dotnet472 correctly, as it seems to try with several versions:

$ WINEPREFIX=~/.wine-octgn winetricks -q vcrun2010 dotnet472

All the time it says Mono is not installed, but the guide explictly says 'do not install mono'
Any clues about what am I doing wrong?

Thanks a lot!
