How to distinguish FULL and UPGRADE versions

[dsl_firecracker]

This concerns AutoCAD LT 98. How do I tell FULL from an UPGRADE version? The CD jacket looks mainly the same. The only difference may be the serial number.
Full? 05708-016008-4901
Upgrade? 05708-016008-4900
Can someone please confirm without opening the CD jackets?
Thanks in advance

Given that either upgrade or full version of that product
has been OBITED (killed by AutoDESK) it probably
doesn't matter much. Also as you will probably not
be able to get an authorization code from them it
isn't important. The contents of the CD's will be exactly the same.

Although the contents are the same, the install is not. The upgrade requires, and looks for, a fully installed previous version. It sounds like you're looking on the net, or elsewhere, to purchase a copy?
