Why do you try to activate 2021? Was is not activated before? If so, it remains activated together with 2022, so you just start it and that's it.

I had an SSD issue, so I had to tweak my PC's hardware and upgrade my SSD to a new one. This means I had to format the PC, having to install both Trados versions again.

Is Studio 2022 activated? Had you installed first S2021 without starting it and then S2022 and activated only this? For what I know this also should have activated S2021. If not, follow the advices https://gateway.sdl.com/apex/communityknowledge?articleName=000001616

Is Studio 2022 activated?
Yes, it was activated prior to me formatting the computer. After formatting it, I reinstalled Trados 2022 after doing the process of resetting my license and waiting at least 30 minutes before imputing the product key.

Had you installed first S2021 without starting it and then S2022 and activated only this?

This I can't recall. I have probably installed both before activating Trados 2022, since I do remember downloading both installing programs at the same time and then doing the reset license procedure afterward. I do remember not running Trados 2021 before activating Trados 2022.

 For what I know this also should have activated S2021.
I am currently running 2021 in the trial version; it is requiring me to input a license key. The only key I have is Trados 2022's key (after doing the upgrade from 2021, the 2021 key vanished from the Licenses in my account). If I attempt to use the S2022 key for S2021, it gives the error I mentioned before.

If not, follow the advices https://gateway.sdl.com/apex/communityknowledge?articleName=000001616

Unfortunately, this wasn't helpful, it does provide guidance on how to reset a license key for using it on another install, which I have already done.

It might help to mention that I have also carefully read and followed what is described here:

Dear Paul

Would someone of you take care here? Thank you.

The way this works is that once upgraded you do lose your 2021 licence and you'll only have one for 2022.  But you do not use the 2022 code in2021 because this will not work.  You should only licence 2022 and once this is activated 2021 should be able to use the fact 2022 is licenced and work for you.

The thread is a little messy and I'm not sure what the status is so can you confirm the following please:

1. is 2022 activated and working ok?
2. can you start 2021 and use it without licensing it?

If the answer to 1. is yes and 2. is no please try deleting this file and then restart 2021:

c:\ProgramData\SDL\SDL Trados Studio\Studio16\Data\Studio.lic

Let me know if this helps and if it doesn't I'll create a case so the support team can help you.

As you've guessed, 1. Yes and 2. No.

So, I deleted the file you mentioned and restarted Trados 2021. Once open, it is still running as a Trial and asking for activation.
