oXygen INSTALLATION
You can download Oxygen XML Editor and test it for free for 30 days but you have to complete the form on https://www.oxygenxml.com/xml_editor/register.html and your 30-day trial license will be emailed to you. You must insert a valid non-disposable email address to receive a license key.
When you launch Oxygen XML Editor for the first time, you are greeted with a Welcome dialog box. It presents upcoming events, useful video demonstrations, helpful resources, the tip of the day, and also gives you easy access to recently used files and projects and to create new ones.
If you do not want it to be displayed every time you launch Oxygen XML Editor, deselect the Show at startup option in the bottom-left corner of the dialog box. To display it any time, go to Help → Welcome.
