Not activated at register during purchase process

A user in a fb group says she can't register PSE  because the activation barcode was not scanned during the pruchase process, AND she tossed the box that the two barcodes on it.  The purchase was more than 90 days ago 

Does she have any recourse to Adobe other than a sob story and hope they "hook her up" or give her a $20 discount?

I have no reason to think she is "pulling a scam"..

Provided is my scan of my pse 2018 just for "an example"...
