I recently purchase Trados Freelance 2021 but have not downloaded and installed just yet because my Trados Freelance 2015 is still there in my laptop. I want to deactivate and uninstall my 2015 version to save up my laptop's space for my new 2021 version. Is it possible? If yes, how so? I will use my Trados 2021 version instead of 2015 version which is already obsolete. Please advise. Thank you.
