Error 80073712 when installing SP1

[Dianepa60]

I have been trying to install SP1 since Apr 2011. I keep getting the error 80073712. I have been able to install all of the other updates.
I have downloaded and run system readiness tool.
I have run troubleshooting/fix problems with windows update
I have run sfc/scannow.
I have run MS Fixit as well.

I seem to have a corrupt manifest file. My laptop came windows 7 loaded so I only have recovery disks and a recovery partition. I don't want to have to do a complete recovery and have to install all my software again.

Here is the message in the checksur file. Can anyone help?

You need to find another PC running the same version of Windows and copy a file from it...
Take a copy of the file
%windir%\winsxs\Manifests\wow64_microsoft-windows-ie-htmlrendering_31bf3856ad364e35_8.0.7600.16444_none_94713718e71db047.manifest
copy it to %Windir%\Temp\CheckSUR\winsxs\manifests\ on the problem PC
Rerun the system update readiness tool
That should fix it
