Success (for offline use): The installer times out on each connection attempt and falls back to a manual or offline activation mode. You will need a valid activation code generated from another machine.
Failure (some versions): The installer throws an error like "Unable to connect to licensing server" and aborts. In this case, you may need to temporarily unblock one or two specific domains, complete the activation, then re-block.
