Upgrade using the web

2007-09-20 05:11:32 AM
I was about to upgrade 4 machines from the web. The web site implies that
you can download the upgrade for a lower price than ordering the DVD.
When downloading the "Upgrade" from the site, it completed very quickly and
was about 5.5MB in size.
I remembered that this is the size of the "Update 3".
How do I download the "Upgrade" for which I recieved the 4 serial numbers?
