Pro licenses are issued to a single technician/support person to use CCC temporarily on an unlimited number of computers. CCC may not be permanently installed on client computers or used for scheduled backups on their computers. The Pro License is great for replacing a client hard drive, making an ad hoc backup of a single machine before servicing or replacing that system, or for a consultant setting up new computers for others.
There are two common configurations where a Pro License is applicable, and each has a different method for applying the CCC registration details.
