Ah - the files are there, but in the wrong places.
Lets try it this way.
Move the rob6491.zip folder to your desktop.
Now Extract all again- to the default location (which should beyour desktop)
Now open an Elevated Command prompt and run the following commands.
COPY %userprofile%\desktop\rob6491\manifests\*.* C:\Windows\Temp\CheckSUR\winsxs\manifests /V /Y
COPY %userprofile%\desktop\rob6491\packages\*.* C:\Windows\Temp\ChecKSUR\Servicing\packages /V /Y
Then close the Command Prompt window, and run CheckSUR again - post the CheckSUR.log file when complete
