After activation you don't need to be online for CbB to keep running normally.

Do that mean I can download the files from one computer and then move them to my DAW??

You have to have a BandLab account using the same email as per your Cakewalk account so that at some future time yet to be decided, all the user data including what previous Cakewalk programs you owned can be transferred to your BandLab account.
You must download and install and login to BandLab Assistant (BA) to download Cakewalk by BandLab (CbB).
You must have BA installed on any computer that’s running CbB at least for the installation and authorisation which takes place automatically. After youve installed CbB you can stop BA from running in the background via an option. From then on you need only run BA to download any new updates either to BA or CbB.
New CbB updates are notified in the appropriate sticky thread above and via BA whenever you run it.

To put this simply, you either have to move your DAW PC to a location with internet, or you share your phone's internet with your PC.

I very much appreciate everyone's sharing experiences and advice with Cakewalk Bandlab.  I'm considering upgrading from Sonar X3 which is currently running fine with win 7, but whenever I've upgraded to a new version of Sonar I've always had several questions and occasionally an installation problem.  If this should happen, who do I call for tech support?

Here is the support form.
