Instalation in a new computer and formatted notebook

At the moment I have Trados 2017 Freelance Plus installed in a slow and old computer.

So, I have upgrade to Trados 2021 Freelance Plus in order to install it in a new fast computer and also in a notebook. The notebook was formatted before returning the license (Trados 2015) 1 year ago.

So, I am not sure about Reset/Deactivate.

How to proceed the installation in both machines safely and promptly in order to follow with my projects in progress? 

 

 Thank you
