Windows 7 SP1 wont install, Error 80073712

Just the one failure in the CheckSUR scan...

Code:

Unavailable repair files:
 winsxs\manifests\x86_723b5e7e66ad7d1d72fad907ca29d689_31bf3856ad364e35_6.1.7600.16664_none_55aea7a4a22ae145.manifest

... and the related error in the SFC scan.

I'll post a fix protocol a little later.

I've uploaded a file - g4naa.zip - to my OneDrive at Noel's OneDrive
Please download and save it.
Right-click on the downloaded file, and select Extract all…
Extract to the default location - which will create a new folder g4naa in the same place.
Open this folder - there should be one folders inside it (Manifests)

Copy the content of the manifests folder (.manifest files) into this folder:

C:\Windows\Temp\CheckSur\Winsxs\Manifests

Now run the CheckSUR tool again (it may take a while)

Post the new CheckSUR.log file, and the CheckSUR.persist.log file.

Good - CheckSUR is happy now.
Please do a Check for Updates, and attempt to install ONLY the oldest update found.
If it installs OK, try the rest.
