Adobe suite License aKey - had one, lost it; Recovery? Discovery?

Pre 2017 (c. 2015) I had installed the suite of apps. It was available Free, as a short-duration promotion. You'd grab it too, yes? Within 24 hours, a link popped up in the open Illustrator, so I could grab the  the registration key.  It successfully ran on my computer. But...
Our server crashed, and I lost all stored files.
I have since downloaded the suite again, and passed the free trial.
I do not see the License key in either of my Adobe accounts.
As the new dowloaded suite simply merged with the old, I am asking whether and where I would find the old Rego Key within one of the sub-folders in the 😧 drive?
If so, in which folder, please?

(I'm a user, not a tech-head) Ayy thoughts/ideas welcome, and "thank you".
