Hi Gael Martin

Please note that when upgrading you do not get to keep a separate license for the old version. In 2018 you have upgraded your license from Studio 2017 to Studio 2019, so you are now the owner of the Studio 2019. You have also purchased an upgrade to Studio 2021 this year, but you have not processed it so far. To do that please log in into your account and go to Products and Plans - Licenses. Once you process the upgrade, Studio 2019 will only work as long as it is on the same PC with Studio 2021 and Studio 2017 (if you are still using it) won't work anymore. If you intend to keep an older version as a separate license, in the future please consider purchasing a new license, not an upgrade.

If you have any questions, please let me know.

Kind regards,

Elisa
