All license keys for Term Licenses must be applied to the product immediately upon receipt of the license key. The time limit for each Term License begins once the license key is delivered and expires on the respective date of the term. Products with perpetual license keys do not have restrictive time limits and should be used instead of Term Licenses in the event functionality is needed past the respective term. 30-day and 90-day licenses cannot be extended or upgraded to non-term or perpetual licenses.
