This won't give you a single-file download, but it looks like copying the files in c:\program files\mcafee\epolicy orchestrator\db\software\current\virusscan8700\install\0000 and running setupvse.exe might work.
You should be able to download an installer package from the McAfee website when you log in with your Grant number.
For example I would log in here:
and it would list what I am able to download.
Hope that helps!
