1. License
<oXygen/> is not free software. You can freely use <oXygen/> for a 30-day trial period. If you wish to continue using <oXygen/> after the 30-day trial period, you must pay a fee.
2. How do I enter my License key?
After you installed the <oXygen/> application you have to get a license file using the same download page. As a result of the request you will receive an e-mail with a license.key file attached. You have to copy this file in your application directory (where oxygen.exe resides) and then start the application.
It's better to copy this file as a backup in a safe location.
3. Extending Trial period
If the period provided by SyncRO Soft is not enough for you, you can extend the trial period by sending a request to support@oxygenxml.com. Please specify the number of days you would need.
