If you have installed Claro v10 for the first time (even if you were already using v9.x) you have to create an account from within the software. That will give you a 14 day trial license. If you are entitled to a permanent commercial or NFR license, contact [email protected] after registration.
If you start the user-interface for the first time after installation, and there is no license installed, you will be led to the login page automatically. Click the “Create a new account” button, and fill in the form (at least the required fields). Submit the form by clicking the “Create new account button”. You now have a 14 day trial license.
