Hi,

I've have been unable to run the "Security Monthly Quality Rollup for Windows 7 for x64-based Systems" for several months now. Other updates install successfully but these always fail with the same error.

2020-01 Security Monthly Quality Rollup for Windows 7 for x64-based Systems (KB4534310)
Installation date: 4/26/2020 12:16 PM
Installation status: Failed
Error details: Code 80073701
Update type: Important

SFC Scan completed successfully.

I've attached SFCFix.txt and uploaded the CBS.zip directory to CBS.zip

Thanks for your help!

I think we've done it! Windows update ran successfully and installed that monthly security rollup.

Thanks for all your help!

Great. I will mark this thread as solved.
Follow the instructions below to cleanup the tools and logfiles used in this thread.
Rename the file FRST64.exe to uninstall.exe and run it. This will remove all files and folders created by FRST and the tool itself.
Reboot The machine to complete.
You may remove all other tools and log files.

Take care.
