Windows Won't Update - Error Code 80073701

I have Win7 Pro 64 bit and the Windows update keeps failing to install one important update.

The update is:

2017-09 Security Monthly Quality Rollup for Windows 7 for x64-based Systems (KB4038777)

The update fails when I initiate the update, and it also tries (but fails) to update on shutdown. The error code is: 80073701

I have followed all of the suggestions found here and elsewhere on the internet, but still no go.

The CheckSUR.log and CheckSUR.persist.log files may explain what the problem is, but I don't know what to do with the info.

Would someone please take a look at the log files (attached) and tell me what it means?

Thank you for any help you can provide.

Hi sevenuser264,

You have quite a few previous updates that do not appear to have correctly installed.
I do not have those required cat/mum files to correct it.

Your best bet is the Sysnative forum, they have a huge archive of these type of files.
they will require you to run thier tool
http://www.sysnative.com/niemiro/apps/SFCFix.exe
include the logs you provide here as well.
