"Agreement" in the drop-down list of "Help" on the tab "Home" opens the window "Agreement" with the licence of the product. On the tab "Agreement" a licence is chosen: "Use free license", "Try all features" for a trial of 180 days, "Use Public Data license" or "Paste license key from clipboard", each where the user may choose it. Below it stands the licence agreement, in a language of choice, with "Agree and continue" and "Decline and close". After acceptance the window says when the agreement was accepted. The tab "Components" shows the parties of the licence, its restrictions, and what it includes and excludes, with "Copy license details". How licences work is described in [[Licensing]].
