NB! The Viking does not work with the latest version of Mac, macOS 10.15 Catalina, so do not update your Mac if you want to use the Vikingen.
The company Codeweavers released a program Crossover mac that can run Windows 32-bit program and it can run Vikingen for pc on Mac Catalina.
If you want, you can test 2 weeks here:
If you are going to reinstall Vikingen then you need new username and password from firstname.lastname@example.org
