After you register the CNET version with your DAZ account, don't forget to eventually also check your "Available Downloads" to see if you have a download waiting. It should be ~ 90MB.

You might think it's the same thing you already have but it's not. It's the full COREL Bryce v5 program, the 5.01 update, the content all in one nice package. More importantly, unlike the CNET version it won't require "Online Activation" everytime it's installed. Instead, it'll just take the serial number alone which you can also find in your DAZ Account under "Available Serial Codes".

You can then decide when version you'd like to keep / archive / uninstall at your leisure.
