.NET 'the reference assemblies for framework ".NETFramework, Version=4.5" were not found
Windows thoroughly confused about this issue.
Fix was to go to a machine with the assemblies and just copy the 100MB over.
c:\program files(x86)\reference assemblie\microsoft framework\.NETFramework\v4.5\

4/2019: found an alternative, with VS 2017 installer you can right click on the right hand side components and hand pick the various .NET components you want to install. what a mess!
