I am trying to install .Net Framework 3.5 (required by our accounting application) on a brand new Surface Pro 3 running Windows 8.1 64bit. When I attempt to install I get the following message.
The following feature couldn't be installed
.NET Framework 3.5 (includes .NET 2.0 and 3.0)
Windows couldn't find required files to complete...........
Error Code 0x800F081F
I have tried everything that I have found on the Internet with no luck. It appears that the problem lies in the fact that Security update KB2966826. There appears to be no way to uninstall this update. This update came installed on the Surface Pro. I have reset the Surface Pro back to factory defaults several times and since the update came on the unit it is installed at every reset.
Does anyone have any ideas as to how I can uninstall KB2966826?
