Why did Photoshop and Illustrator disappear after an update?

Episode 1470 (1:51:10)

George from Victor, MT
Affinity Photo

George bought a computer that had Photoshop and Illustrator on it and the software disappeared during an update. Leo says that if he bought a computer that had an illegal copy on it, he would expect Adobe to notice that there's a pirated copy when he used it. If he can get the serial number, he can then reinstall it with the proper number. Leo also suggests that he try using Affinity Photo instead.
