Hi Reiko Mitarai

You only have one license linked to the gmail you are using on Community, not 3 separate licenses.

As you can see yourself when you go to Licenses tab, it is just the one license, a Trados Studio 2022 Freelance Plus. This license type allows you to install and activate Trados 2022 on two separate computers at the same time, but nevertheless it is just one license, you just activate it on two devices using the same activation code.

As a rule, once you process an upgrade from a previous version of Trados to the version you purchased the upgrade for, the system generates a new activation code which works only for the upgraded version.

What we offer and can be done is to install two consecutive editions of Trados and the older one activates via the newer. if the upgrading was done for consecutive editions and did not skip a version. You can read more here:

This means you can install Trados 2021 on the computer where you activated Trados 2022 and it activates via Trados 2022 - it cannot be activated with an activation code. As I mentioned above, the activation code is valid only for Trados 2022.

If you have a different RWS account where you have individual licenses for Trados 2021 and Trados 2019, then you need to activate them with their respective activation codes.

If you have other questions, please reply here.

Best regards,
