I try a lot of times.

Flexsim 5.0's licensing scheme allows for a lot of flexibility in various licensing models, including the ability to limit the number of returns and rehosts of licenses. Our sales team can now distinguish licenses as "professional" (which can only be activated once) or "enterprise" (which allows returns and rehosts).

You can contact your distributor, who will in turn contact our sales team directly in order to set particular licenses to professional or enterprise.
