Question: What is an "Extended Upgrade Key"?
A Extended Upgrade Key is a code that may be used to activate Foxhound Version 4 as an Extended Edition copy after upgrading an existing copy of Foxhound 1, 2 or 3.
The "Basic Upgrade" and "Extended Upgrade" prices apply to any previous version of any edition
of Foxhound whatsoever (Rental, Basic, Extended, Free Trial, Beta Test, etc.). In these cases
an existing Foxhound database must be available to be read by the Foxhound 3 installation process.
