I'm also having a similar kind of problem. The only thing is that I don't get an error code and Windows Update doesn't display the KB2952664 update. I tried re-installing it along with other updates to fix some issues with Get Windows 10 app.
Is there any way to download the update manually or fix Windows Update? I tried resetting Windows Update components and Windows Update troubleshooter but no luck.
Here is more information about my problem :-
