Note that Computer linking is the default option available to all Image-Pro licenses without the need for an additional purchase.
Choosing this option means you are requesting a USB Dongle (HASP HL Max) as a secondary linking target for your Image-Pro license at additional cost.
Image-Pro is licensed by “linking” licenses to a valid target. License linking is a flexible and reversible process that allows the un-linking of licenses from one target and re-linking of them to a second target whenever, and as often as you like.
