Supports creation, deletion, and activation of rows in
the etsysActivationKeyTable.
An instance of this variable may become active(1) only
when there is a corresponding etsysActivationKeyValue.
For some key formats, the etsysActivationLicenseString
may need to be set to a matching vendor-supplied value.
Note that a row with an active(1) status may contain a
demo key that has expired, and that no longer provides
access to any features.
