Translate Archicad 23 Reference Guide to Vietnamse

[Anonymous]

Hi everyone!
In my Current Project, i'll create a copy of Archicad 23 Reference Guide to Vietnamse.
I've use it for Main content which i created on.
I have worked with the Publisher to print this series.
In Vietnam, only Publishers are authorized to publish and promote nationwide.
However, on the first pages, I saw the words "Copyright © 2019 by GRAPHISOFT, all rights reserved. Reproduction, paraphrasing or translation without express prior written permission is strictly prohibited."
so I want to ask where I have permission, and who can I contact to solve this problem, thank you.
