A manual install of the bottom (Windows) patch fails. The error message reads that it is not intended for this computer.
Apple software update (in windows) finds the same patch and acts like it is intalling it, asks for a reboot, and makes no note of installation failure. But, running Apple software update again after reboot finds the same patch. Apple needs to update the patch to allow installation on the new 17.
I would guess it is a older model or a 15. This is not user error. It is a bug (one that will drive you to near madness if you have 8 hours on a plane and 100 Outlook email to get through).
