When executing the installer, the Windows SmartScreen Filter may issue warnings . This is because the installer itself is not signed. Code signing certificates are expensive and unfortunately not an option for me at the moment. You can check the integrity using the PGP signature provided .

To bypass the smartscreen filter, click on "more information" and then on "run anyway".

If you have any further questions, contact me.
