Live Update Fails to Update N360; New Install Windows 7

I just installed Windows 7 (as a stepping stone, hopefully, from Win XP to Win 8, then to Win 10).  All went smoothly installing Norton SS ("You Are Protected"), until I ran Live Update.  It successfully processed 21 updates but failed on the 22nd, with the message:

Live Update failed

I guess I need a version of Norton_Download_Manager.exe for Win 7.

But it is just a guess, and I had a heck of a time finding the right one for my XP system (which I am now back in [dual boot]).

Can anyone help?

Thank you,

Robert
