There is a thread in our forum about the same problem....... unable to install KB3093266.
The only suggestion that did work for some members in that thread was to do a system file check....... sfc /scannow.
Do you know how to do that ?
In another forum, there is one reply which was marked as Most Helpful. A couple of members there said " it worked ".
Have a look at it. See if that helps.
