  1. I have tried.
    1) installing via Windows update or
    2) downloading stand-alone update installer will install this update.

    This update is the only one to have ever failed both installation methods.
    I’m convinced the issue is with this update and NOT my x64 Windows 10 Version 1709 (OS Build 16299.192) PC.
