Answer: Foxhound comes in two parts: A setup file and a registration key.

The setup file is available from the Foxhound web page.

A registration key can be purchased, or obtained for free, as follows:

Basic Edition registration key $195.00

Extended Edition registration key $395.00

If you already have the Basic Edition installed, you can upgrade by purchasing an Upgrade Basic To Extended Edition registration key for $200.00

Evaluation Edition - ask Breck.Carter@gmail.com for a free registration key. If you're in a hurry, you can buy a registration key for $4.95 It is also possible to renew an expired Evaluation Edition; ask Breck.Carter@gmail.com.

The Beta Edition of Foxhound will be available from time to time, and when that happens you can ask Breck.Carter@gmail.com for a free registration key.
