Why can't I install Adobe Premiere?

Episode 1230 (2:28:18)

David from Venice Beach, CA

David is trying to use Adobe Premiere and it stops working. Leo says that Dave bought a serial number, and if it doesn't have disks, it won't work. That's Adobe's copy protection. Leo recommends just using Adobe Creative Cloud instead. He can put it on two computers. If his friend sold him his copy, he needs to give him the disks to install it as well. He'll probably have to contact Adobe and transfer it as well.
