There’s no way to prove you don’t own it at this point, as you’re not required to keep records beyond a certain point (depends on jurisdiction) and creating backups of owned media is lawful.
Let’s say I bought a book. A real hardcover copy of Harry potter and the fucking scarecrow (again).
Do I own it?
I own the physical media, the author or publisher can’t stop my from reading it, or even reading it out loud to a crowd of people. They can’t remotely delete the pages either.
I don’t own the copyrighted text but I do, in fact, own the copy of the book.
Is it a perpetual license that let’s me read the book as long as the physical media is in my posession?
Same goes for the CD. It’s not rented and it’s not a license, OP owns it and can use it. Adobe develops and owns the source code that they compile, package and sell.
Unless you need to prove you own it in court.
