Problems Updating N360 On Dial-up Connection

Gentlemen,

This is a problem you're not likely to see much of anymore -- I have dial-up.

The specific problem is that I can no longer update Norton 360. The computer I'm using right now had Norton 360 2013 installed on it from a retail disk. I renewed the license in 2014 and the product has been maintained through Live Update since the beginning. I run LU every day and Sunday morning I was expecting to get the usual 4 or 5 MB update, but instead I get a figure of something like 230MB!

There is no way that my connection can go uninterrupted long enough (maybe 15 hours!) to go ahead with this update. The best I can do is around 160 -- 170MB before the connection drops. Since LU does not support a resume feature, it just starts over from zero when the connection is reestablished.

I just got a new computer running Win7 64-bit and I can't run Norton on that either. The updates are just too big. Every time the connection drops when I tried to run LU on the new machine the LU box says that there is a patch (for what?) that it wants to install. I've let it do this three or four times but it makes no difference.

The only solution that a Norton Live Support guy could come up with was to download the latest version of N360 from a library computer. That would supposedly make the updates smaller. I don't know exactly the version currently running on my old (this) compter, but it's been kept up to date and I still got the 230MB offering from LU. He gave me a link to what I'm guessing is not the latest version of N360, but some kind of download manager -- which does not support a resume function either -- that will in turn download the actual N360 program. I doubt very seriously that the library will let me run an executable file on one of their computers in order to download the latest N360.

No, I don't have any friends in this city who I can ask to download it for me. And no, I don't have a laptop that I could take to a wi-fi hotspot to download it.

I'm wondering whether there are any work-arounds to this problem or am I screwed?

I have a freeware download manager that supports resuming broken downloads, so it can't be that much trouble to incorporate this feature into a piece of software.
I can't believe that a "sophisticated" program like N360 (and presumably other Symantec titles) make you start over from the beginning if a download gets interrupted! I still have something like 220 days left on my current Norton subscription. Am I going to have to abandon a product I like just because there's no longer a viable option to update it?

Any useful thoughts on this matter will be appreciated.
