For anyone who cares or doesn't already know...

It looks like the product ps_ap075 (Bryce 5 Hi-Bandwidth Download) that was there earlier today has now been pulled from the DAZ store as the free version has replaced it.

Additionally, I found the "REAL" DAZ Bryce 5 installer that doesn't require (internet) product activation after installation in the "Available Downloads" section of my account after registering the version downloaded from CNET. 

This free DAZ version is just one piece (~ 90 MB) and provides an automatic installer.

I just had to provide the serial found under "Available Serial Codes" section (which I have also archived for offline use) and that's it.

Then you can delete the version from downloaded from CNET and keep the version downloaded from DAZ instead.
