Hi Tom, No errors detected
is always a nice thing to see!
I can't see anything of concern in your CBS log and your CheckSUR log is clean so in theory, the update should install now. But Windows Update can be a right pain sometimes so who knows! Try installing the update and let us know how you get on.
There was file corruption on your computer, which we fixed, but at this stage it is impossible to tell whether it caused your problem or not as we haven't tried updating. My money is on that being the cause though
