What happened to my serial numbers?

[AJaxx]

I can't locate my serial numbers for PE 18 or PE 20.  I have serial numbers for PE 13 which I upgraded to PE 18 online and then PE 20 in May of 2020.  Importantly, I would like to install PE 20 on my new laptop, but I can't locate the S/N.  I thought Creative Cloud was supposed to indicate these purchases, but it doesn't.  Right now, I am using a trial version of PE 20 on new laptop, but I'm not too keen on having to buy it again.  Thanks, Jack

If you have registered the programs with Adobe, the serial numbers should all be in your Adobe.com profile.  Click this link, and if necessary sign in to your Adobe account.  Your serial numbers should then be displayed.
