The error is this:
'This setup requires the .NET Framework version 2.0. Please install the .NET
Framework and run this setup again. The .NET Framework can be obtained from
the web. Would you like to do this now?'.
So the .NET 2.0 version lies inside the Features of the server (.net version 3.5, contains .net 2.0 and 3.0).
in Server Manager go to, Add roles and features, then next until you find the features, and in there select the ".NEt framework 3.5" .
Wait for the install to finish.
(if you're on-premises you would need the Windows server 2012 ISO and to do this http://www.askvg.com/how-to-install-microsoft-net-framework-3-5-offline-in-windows-8-without-internet-connection/ or
Or in a command prompt with elevated privileges run:
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:x:\sources\sxs
After the 3.5 installation run the install again and you shouldn't get any more issues.
