The full name of the update is:
Security and Quality Rollup updates for .NET Framework 3.5 SP1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, and 4.7.1 for Windows 8.1, RT 8.1, and Server 2012 R2 (KB 4340558)
In an attempt to correct this error, I have:
1. Run the Windows Update Troubleshooter
2. Run"dism /online /cleanup-image /restorehealth"
3. Stopped and restarted services pertaining to Wnidows Update -- wuauserv, bits, cryptsvc
But none of these steps resolved the problem. This particular update downloads, but simply fails to install.
I did a clean reinstall a couple of months ago, so I do not think my system is at fault here.
Is anyone else experiencing the same problem with this update?
