.NET Framework won't reinstall

On a Windows 7 SP1 Pro machine, I uninstalled .NET Framework 4.6.2. When I go to reinstall It goes through the install process to a point and then rolls back saying there is a Windows error. I have run the .NET fix tool, the .NET clean up tool and nothing seems to allow the reinstallation of the .NET framework 4.6.2. This component is needed to run QuickBooks on this PC. Would like to avoid reloading Windows over this if possible.

Open a command window and run

sfc   /scannow

Google this command on the Internet for lots more information and make sure you have a good backup before you run it.  You've said you've got a Windows error so let sfc see if it can find it and fix it.

Actually that's my bad-I have run that command as well as The WMI diag tool. SFC found nothing. None of the utilities I have tried have been effective or shown a result that would point me in any specific direction. Sorry for neglecting to mention that. Thank you for your response!

You say there's a message indicating a Windows error?  Any code with that message?

Also download the UBCD  http://www.ultimatebootcd.com/download.html and make the CD and boot from it and run memtest.  (Ask for instructions on how to do this if you need to).  Let's do some basic tests and check the hardware out.  Also test the hard disk using the appropriate manufacturer's tool on the UBCD.

I appreciate the responses-I have not found any evidence of hardware issues-hard drive, memory, CPU.
I have run all of the diagnostic and repair tools I can find. The client needs resolution and full function. We have decided to reload Windows for expediency.
I am closing this question.
Again thank you for your responses and solutions
