.NET Framework 4.0 installation failures

Question

I have been unable to get the .NET 4.5.1 updated on my computer:

OS Name Microsoft Windows 7 Home Premium

Version 6.1.7601 Service Pack 1 Build 7601

System Type x64-based PC

Processor Intel(R) Core(TM) i5-2500K CPU @ 3.30GHz, 4001 Mhz, 4 Core(s), 4 Logical Processor(s)

Have attempted all the usual MS DotNet Fixit repairs and other common fixes I can find in the forums.  sfc scan shows no integrity violations.  Lots of hard drive space left.  Followed Aaron Stebner's weblog and used his tools to get back to 3.5 install, and verified the existing 3.5 install good using his tool, but now can't get any .NET versions above that installed  Have attempted using Windows Update and using full downloaded versions.  

Current log file has this when trying to update from .NET 3.5 to latest:
