Choose from two license types: –– Fixed, perpetual license: This allows you to run the application in the X-Series analyzer in which it is initially installed. –– Transportable, perpetual license: This allows you to run the application in the X-Series analyzer in which it is initially installed, plus it may be transferred from one X-Series analyzer to another. Options can be added after your initial purchase. All of our X-Series application options are license-key upgradeable. The table below contains information on our fixed, perpetual licenses.
