SQL server 2016 installation freeze

just had the same problem which is why I found this question. Fixed the problem by closing the original media install menu window (where I'd selected "New SQL Server standalone" which is the first option). The install window then carried on.

My problem was that the installer tries to download Microsoft R Open , if you have a slow connection you will see the installation freeze for a very long time without any progress bar updates or so . I fixed the problem by deselecting all R components since i dont need them then the installation went smooth .
