What type of installation did you try? It looks like the installation is failing for lack of a valid .NET 4.7.2 installation. I would expect the installers except the ZIP file "unplugged" installer to get .NET 4.7.2 installed correctly for you automatically. However, if you are using the ZIP file "unplugged installer" then you need to read carefully the pre-requisites at the bottom of the page, which include directions for how to install .NET 4.7.2:

You can see on this page, that it suggests the following link for installing .NET 4.7.2 your self:

I guess even if you are not using the ZIP file "unplugged" installer, I would try installing .NET 4.7.2 yourself until you can get it successfully installed and then try installing Skyline again.
