KB4493472 Install fails

[dubiousfood]

This server is failing on some selective updates since June of 2018. Now it fails on the latest security rollup--KB4493472
I have attached the cbs.log (scratch that, attaching Windows update as the CBS log is 98MB) and suspect it's due to an AMD install failure from KB4284826

Exec: Resolving Package: Package_3_for_KB4284826~31bf3856ad364e35~amd64~~6.1.1.4, Update: 4284826-3_neutral_LDR

I might be wrong, but in case I am not, I also attached a SearchReg.txt from FRST

Thank you anyone who may have some tips or ideas thank you.
Also, I did extract the update and attempt to run the .cab, with the same assembly missing error
Thanks.

Hello and welcome!

Step#1 - FRST Fix
NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system
1. Please download Farbar Recovery Scan Tool and save it to your Desktop.
Note: You need to run the 64-bit Version so please ensure you download that one.
2. Download attached file and save it to the Desktop.
Note. It's important that both files, FRST64 and fixlist.txt are in the same location or the fix will not work (in this case...the desktop).
3. Run FRST64 by Right-Clicking on the file and choosing Run as administrator.
4. Press the Fix button just once and wait. If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.
5. When finished FRST64 will generate a log on the Desktop (Fixlog.txt). Please post the contents of it in your reply.
6. Try updates and if any fail, attach CBS.log.
