Win 7 SP1 Update Fail (80073712) - 2 Empty Manifest Files

I working on a client's machine attempting to install SP1.

As per the attached CheckSUR log - two manifest files are empty and I get the error msg - CSI Manifest Zero Length.

There is a third manifest with a similar name - see attached png for list. The 16385 file is good - 16597 and 20717 are empty.

Here are the contents of the 16385:

<?xml version="1.0" encoding="UTF-8"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v3" manifestVersion="1.0" description=".NET Framework component" displayName=".NET Framework mscorlib.Resources" copyright="Copyright (c) Microsoft Corporation. All Rights Reserved." isolated="false">
<assemblyIdentity name="mscorlib.Resources" version="6.1.7600.16385" processorArchitecture="msil" language="en-us" publicKeyToken="b77a5c561934e089" />
</assembly>

I cloned the 16385 twice changing the version number to match that of the other two files (16597 & 20717) and put the new files in the C:/windows/temp/checksur/winsxs/Manifests folder but then I got the error "CSI Located Replacement: Invalid (Catalog)" error in the Checksum log.

After running Checksum SP1 install fails with the error code 80073712.

In looking at other posts I'm hoping that someone can provide me with accurate versions of my two empty manifest files.

Thanks so much in advance! This is driving me crazy!!!

Thank you so much!

The files you provided are identical in content to the two I created but yours did the trick! I don't get it.

Attached is the new log.

Where did you find those files? Are they somewhere on Microsoft's site?

I'm going to attempt the SP1 update yet again. I will keep you posted. Thanks again!

SP1 installed - yay! Just now installing all subsequent updates. You are a god!

All remaining updates have been installed successfully! Thank you so much! Next time you are in NYC I will buy you a beer!
