Versa Magic is included with the standard Versa Note installation. A SolidWorks Document Manager Key is required (available to SolidWorks users with an active subscription). You can request a key here: https://www.solidworks.com/support/subscription/key-request/
Trial users can use Versa Magic, with limitations, at any point during the trial period. Migration users are entitled to unlimited use Versa Magic at no extra charge for 1 month following the completion of the note migration process, and when this period ends you may purchase usage credits and continue the magic with an Enterprise License.
