Your long shot did not work - unregister/re-register the files listed above made no difference.
Testing results:

Next day
Booted to Win7 (as above) > double-clicking AutoPatcher.exe has no effect - program does not start - period
Rebooted to Win10 (upgraded 8.1) > AP6.2.02 > Turn OFF Windows Defender - again > AP6.2.02 started > No updates required - items downloaded previously all blue > Next Install updates > List of available items: Windows XP x64 & 2003 x64, Microsoft Windows - Updated Components, Microsoft Office Addons, Microsoft Windows Admin, and Windows Addons > Exit
Things appear to be working OK.
Next day
Booted to Win10 Insider Preview Build 14366 64bit > AP6.2.02 > Turn OFF Windows Defender - again > AP6.2.02 started > Crash Handler Yikes! > Where: APInitialize.PrimaryInit() At Line 142 Error Code: 0x1E1: Invalid Picture > Quit
Later
Booted to XP Pro x64 w/SP2 > AP6.2.02 > Download Updates: Odd - top item = AutoPatcher Engine 6.2.0 (Replaces Apup) shown in RED - but that is the version that is running - why misidentified? > Four other items shown in Red - checked and downloaded > Install updates > Listing shown appears to be correct purposes of these tests.
Final decision
I can't prove it but I have come to the conclusion that the problems occuring in both versions of AutoPatcher are the result of my having installed the cumulative update KB3125574.
