Boot Camp 6 update for Windows 10 not installing
I have a Macbook Pro w/ Retina Display (the first one - can't remember the year) and it has Windows 10 installed. When I open Apple Software Update in W10, it shows I have the Boot Camp 6 Update for Windows available to install. I select it and click the "install 1 item" button... it seems to run, then asks me to reboot. However, after my mac reboots (into W10), when I open the Apple Software Update, the BC6 update is still there.
Any help with this would be appreciated.
MacBook Pro with Retina display, OS X El Capitan (10.11.5)
