Questions about the license.

I used to own a Computer A, and there’s a Soft-elicenser A which is registered to account A.(Which I don’t use any more, both the computer A and account A)
Now I get another Computer B, and there’s a Soft-elicenser B registered to account B on this Computer.
What I want to do is to remove the Soft-elicenser B from account B, and reconnect it to account A. So I can purchase Dorico and register it to account B not account A.
Could anyone tell me how I can do it?

The easiest way is to contact Steinberg customer service. If you’re in the US, they have a phone number.
