<oXygen/> is not free software and requires a license in order to enable the application.
For demonstration and evaluation purposes a time limited license is available upon request from the <oXygen/> Web Site http://www.oxygenxml.com. This license is supplied at no cost for a period of 30 days from date of issue. During this period <oXygen/> is fully functional enabling you to test all aspects of the application. Thereafter, the application is disabled and a permanent license must be purchased in order to use the application. For special circumstances, if a trial period of greater than 30 days is required, please contact <support@oxygenxml.com>. All licenses are obtained from <oXygen/> Web Site (http://www.oxygenxml.com).
Once you have obtained a license the installation procedure is as follows:
Procedure 2.10. License Installation
Save a backup copy of the message containing the new license file.
Start the <oXygen/> application.

If there is a new install of the editor then it will display automatically the registration dialog when it is started. In the case you already used the editor and obtained a new license, use the menu option Help/Register to make the registration dialog appear.
Paste the license text in the registration dialog, and press ok.
