CAD DESIGN SOFTWARE products use Macrovision FLEXlm to license all of its products. FLEXlm can be used in either locked or floating configurations.

Locked licensing dedicates a license to a particular computer or CDS hardware dongle key.

Floating licensing allows multiple users to share a license over a local network via a server or host computer and grants or denies licenses based on availability. With floating licensing, the license is assigned to the server name and MAC address and is defined as the license server, and each client workstation running the CDS requests licenses from the server as needed. The number of available seats are stored in the license file.

The license key can be generated from the Ethernet address (MAC) of the computer’s network card or disk volume serial number (DOS Prompt = c:\dir), or from the serial number of a CDS hardware dongle attached to the computers parallel or USB port.

You can purchase a license with full functionality or with one or more limited features. The license keys in the license file activate only the purchased products. CDS typically issues FLEXlm licenses on a yearly basis. Trial software evaluation licenses are generally issued for 15days.
