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.
