How do I fix this manifest error in my ChueckSUR.log?

My windows update isn't working. I've been following this guide and its been great for fixing almost all the errors in my CheckSUR.log, but I can't figure out how to fix the last error. Here is the contents of the log:

The key line being that unavailable manifest file at the end. The problem is, I don't know where to find that manifest file so I can run SURT on it.

How can I fix this error? I'm on a Windows 7 machine version 6.1 with service pack 1.
