When you run CA Agile Requirements Designer for the first time, the License Wizard opens. Activate one of the licenses online to complete the installation. You can open the License Wizard from the Help menu in CA Agile Requirements Designer to change licenses later. For example, you start with the Trial License, then switch to the Viewer license, and later buy a Named License.
Viewer license
The Viewer license allows you to use CA Agile Requirements Designer in a limited capacity. Choose this license to be able to view flows created by team members who have one of the other licenses. You cannot save or modify any viewed flows, nor can you create automation, nor run optimization. You can use the Viewer license indefinitely.
