I don't quite follow what you're asking, aside from the naughty request.
You can't get the update for Norton and then put it back onto an ME installation - the whole reason you're told that it will only work on 2k or XP is exactly that, it will only work on 2k or XP.
So you have a choice:
a) live with the unupgraded Norton and ME
b) switch to XP or 2kSP3 and upgrade Norton
You can't have Norton 2006 on XP, and nobody here will help you source a naughty copy of anything. Seriously though, ditch ME before you're machine dies in a flaming heap. If you use your machine for work purposes or work for the gov't or education, your employer might be able to swing you a legal copy under a Volume License agreement.
