The License Panel is where you enter your License, which is required for access to most of the Lessons in the Rosetta Stone. Without a License, only demo Lessons will be available.
Enter your License name and License password in the "Name" and "Password" fields. To install the License on your computer, click on "permanent installation". If you click on "this session only" (or press Enter), your License will be temporarily installed, and you will be prompted to enter it again when you restart the program. To remove an installed License, enter your License password (your License name will already have been automatically entered), and press the "delete" button.
If you do not have a License, you may simply close the License Panel and proceed to the demo Lessons.
