Answer 2
Hi nanof1,
Welcome to MSDN forums.
Some clarification with you
What is your OS?
Based on your description, it seems that your issues might be caused by installation of .net framework 4.
I would provide your some suggestions here.
1, you could type
%systemroot%\Microsoft.NET\Framework64 on your command line to check which versions of .net framework have been installed on your machine.
2, then, could you please check whether .net framework 4 is installed correctly on your machine or not.
You could download .net framework verification tool from Microsoft.

Try to clean your "%temp%" folder (Start Menu >> Run >> Type "%temp%")
The above step could ensure your installation log is only including the latest installation logs.

Run your setup file

5, re-install Microsoft .NET Framework 4 again
It will create a file named %temp%\vslogs.cab on your system.
If it does not work, you could refer your log files to narrow down your issue or upload your log files via Skydrive in your reply.
Or you could send your log files to me. (My E-Mail:
