Actually it is a lot easier than all that, All you need is a good copy of the file to replace it with. So I pulled the 2 files you will need off of a good Windows 7 64bit in vmware, I attached the files for you.
Extract both files, then copy and paste them to
C:\Windows\servicing\Packages
If you get a permission denied error, then let me know, you will have to take ownership of that folder and I have an easy right click menu option to do that, and I will post that if you need it.
Once you replaced the 2 files, reboot and run the scan again and see if it is all good
