LMC, welcome to the Seven Forums.
What happened is your laptop has switchable graphics and will only work properly with the driver
from the laptop manufacturer, in your case HP (or any other laptop with switchable graphics). Problem is that WU is essential stupid in that it doesn't know that and only sees one or the other of the video cards in the laptop, and as a result offers and installs one that won't work with it.
In this case stop trying to install it as it will never work. Just hide the update in WU so you don't see it and only ever install a video card driver update from HP.
