I wiped the hard disk of my Mac mini and am now re-installing my software. I am now wanting to re-install Dorico SE and although I see it listed under my products, where do I get the key I need to download it again.
Sign in to the Steinberg Download Assistant application.
You don’t need a new key: simply install Dorico SE and run it, and you’ll be prompted to sign in with your Steinberg ID (which is the email address and password you use to log in, e.g. to this forum), and that’s all there is to it.
