It is with regret that I have to concur with Tom here.
have also looked for the update file on my own system, in my update repository and on a separate Windows 7 install, and cannot find the exact package files needed for your system.
Normally we can fix this error by downloading the package files ourselves and replacing them on your machine. Unfortunately, since we cannot find the original package, we cannot replace it on your system.
I believe I may have found the files. Please hold off for now, I'll get back to you in a minute.
