To download this update, it says to use Steinberg Download Assistant. I start it, I get a "Sign In" button, I click on it, I get in my browser the message "Authorize Steinberg Download Assistant

To authorize Steinberg Download Assistant, you must allow your browser to open Steinberg Web Launcher. Once authorization is completed, you can close this page and continue working with Steinberg Download Assistant."

I have no idea what this means or how to do it. Please advise.
