Licensing and demo mode
A license is a contractual agreement between Wordfast LLC and the user to use the WFS software within certain limitations. A license is materialized as a code issued by the licensing party—usually Wordfast LLC—in response to a given Install number. The Install number of a WFS installation is found in the Setup > General pane. That number, as well as WFS’ version number, have to be provided to license Wordfast Server.
To get your license number: log in at www.wordfast.net with the credentials you obtained when purchasing the license. Click "License / relicense an application".
