Activation error message "The product key has been activated the maximum number of times" & "Unable to activate the product key. Activation cannot be performed as the quantity is not sufficient."

The below error messages indicate that the license has been activated the maximum number of times permitted.

Single-user licenses may be activated on two machines, provided the software is used by a single individual.
Concurrent-use licenses may be activated on 1 machine.

Error messages:

Single-user license: The product key has been activated the maximum number of times
Concurrent-use license: Unable to activate the product key. Activation cannot be performed as the quantity is not sufficient.

Solution: You will need to deactivate from within the program or using your web browser:

The following scenarios could cause you to see the error messages:

You have already activated the maximum number of times with this product key.
You reinstalled or reimaged Windows before deactivating the license. Now you have an orphaned activation.
The computer crashed/died/was replaced. Now you have an orphaned activation.
One of the three locking criteria (MAC Address, the processor ID, and Windows UUID) changed on your computer to cause the previously activated license to be invalid. These locking criteria lock the license to the computer. If any of those change, that activation is no longer valid and the license must be activated again. The previous license becomes orphaned.
