Issues installing .Net Framework

A client has been having issues updating Microsoft Security Essentials on his Win 7 64bit computer.  We get the error message 80070643 which also refers to .NET Framework.  Couldn't uninstall MSE in programs and features.  Researched it and finally was able to remove it.   Tried to reinstall and get error code 0x8007063.

Tried to repair .NET Framework to no avail -  https://support.microsoft.com/en-us/kb/976982
Method 1: Fix MSI software update registration corruption issues
Method 2: Repair the .NET Framework
Method 3: Uninstall and reinstall the .NET Framework
Issues with .Net Framework 1.1, I believe I installed 3 and when I go to Windows update Microsoft .net framework 4 client profile for windows 7 x64-based systems (KB3063917) it fails with error code 80070643

Feel like I am going in circles and I really need some help.
Thanks,
Mags

Do you have any other anti-malware or anti-virus programs installed?

Also found this article: http://www.brighthub.com/computing/smb-security/articles/69215.aspx

There seemed to be some good tips in the article as well as in the comments.

.NET 1.1 is dead and gone and does not go on Windows 7 or 8.

Go into Programs and Features Windows Features and uncheck the two .NET Framework settings (V3 and V4).  Close out, shut down and start back up.

Go back and add the two .NET Framework settings. Use the default add. Close out, restart and .NET Framework should reinstall.

MBAM...this has never seemed to interfere with anything.  I exit MBAM before trying to install.  I will uninstall then try again.

Hey John...I do not see either of the two .NET Framework settings (V3 and V4) - no reference at all to .NET Framework.   In regedit this is what shows in the registry.

Check Windows Features again (Programs and Features -> Windows Features on the left side). That is built into Windows and how .NET gets installed. I was not pointing to the registry.

John I was able to uncheck 3.5.1 - the only one that was there.  I only provided the registry information because I thought it may be helpful.

jcimarron this link http://windows.microsoft.com/en-us/windows/windows-update-error-80070643#1TC=windows-7 seems have a broken link.  The other I don't believe I have tried.

John I will run the above.

Thanks guys!

When you run .NETFX Verifier, please list (on a sheet of paper) all the versions it recognizes on your computer and post back here.

Also you are correct for Windows 7 (I use Windows 8.1 now). Only .NET V3.5 shows up in Windows Features.

If you uninstall .NET 3.5 and reinstall it and then go to Windows Updates, it should install V4.5

John following your directions to -
Go into Programs and Features Windows Features and uncheck the two .NET Framework settings (V3 and V4).  Close out, shut down and start back up.

Go back and add the two .NET Framework settings. Use the default add. Close out, restart and .NET Framework should reinstall.

Did not allow me to install .NET Framework 4.

I used Method 3 above to uninstall before.

Will try the above.

That sounds OK and if there were no errors, then these versions should be working fine.

So then does Windows Update offer .NET V4 (4.5) in Recommended Updates? If so, install it.

Here is a Microsoft Link for V4.5.1

Both the links in my post http:#a40832896 work on my PC.  Neither opens a new page.  The first under .NET Framework  offers a drop down few paragraphs.  The second is a link to a download for the diagnostic.

You may have to do Windows repairs on your computer. .NET Framework works well on Windows 7 and Windows 8.

Try System File Checker:  Open cmd.exe with Run as Administrator and run SFC /SCANNOW. Allow to complete, shut down, start up and test.

After that, if SFC does not work, run Windows 7 Repair Install. For this, you need a working recovery partition or the Windows 7 DVD. Here is a Seven Forums Tutorial to assist.

The link opened for me but when I clicked on "The steps to resolve the problem are intended for advanced users. If you're not comfortable performing these steps, ask a friend or support professional to help you. You'll find the steps in the .NET Framework article on the Microsoft website."  the .Net Framework link says "This Page does not exist"

Even though the Windows Update troubleshooter said it repaired things I still can not update .Net Framework and still get code 643.

Continues to feel like I am going in circles.

I do appreciate all your help.

John - just did a sfc this morning - no issues -  integrity fine.  This is the computer I recently did a Repair Install on.  I guess the only thing left is to do a clean install unless you have other suggestions.

He is considering waiting until Windows 10 comes out.

JohnBusiness Consultant (Owner)Commented:
Yes, when the repair ideas fail (and they can fail), then back up and fresh install is the most stable thing to do.
