Installing Opus 12 Pro Edition on second PC

I have a single licence version of Opus 12 Pro Edition on my desktop. I have not installed the companion version on a laptop, but would like to install it on my separate desktop which I use only as a media server. Your FAQs imply that you will allow this.

How do I do it? Must I have email access on this media server?

Please advise. Thank you.

Just install, activate with your existing registration code as usual and you're good to go.
Installations won't interfere with each other (Opus is not obnoxious about these things like some other software).
