  • If it says “Perpetual” as shown above then the software will *not* stop working due to an expiration date. 
  • Two lines below that is a line ‘To be used between:’.  That line just reflects the contract period, and not a license expiration date.  In fact when the 'to be used between' end date is passed, the next time a job is ran the Perpetual status of the license will automatically cause the ‘To be used between:’ end date to be extended for another year.
