Have you ever needed your serial number and not be able to find it? It's happened to me more than once. It usually happens when I buy a new computer and am trying to reinstall the software.
There is a free program called License Crawler that will search your computer and find this information for you.
Retrieving your lost serial number has never been so easy!
