3. What’s the difference between buying and leasing a license?

A purchased license has no expiration date. Registered license holders also receive a fifty percent discount on upgrades to new versions.
Leasing is only possible if you purchase at least five licenses. These licenses can then be used for exactly one year after the purchase. The subscription is extended automatically each year unless you cancel at least two months before the extension date. Leasing license holders always receive a free upgrade to the newest version.
