A Perpetual License is a lifetime license purchased a single time. Perpetual Licenses come with 12 months of free updates. Once those 12 months have passed you retain ownership of you license and can continue using it.
However, to ensure you have the newest version you must purchase an update plan to continue receiving updates. If you choose not to purchase the update plan you will always have access to the last update version at the time your Update Plan expired.
A Rental License can be purchased for short term usage. There are 30 Day Rental Licenses available. Your 30 days begin upon license activation, NOT at the time of purchase.
*NOTE* Rental Licenses must be activated with the license code NOT the email address and password.
