Sometimes you need to unregister your license key, for example to release a floating license to be used by other user and still use the current <oXygen/> instance with an individual, Named User license, or to transfer your license key to other computer before other user starts using your current computer. This is done by going to → +oXygen+ to display the license registration dialog, making sure the text area for the license key is empty and the checkbox Use a license server is unchecked, and pressing the OK button of the dialog. This brings up a confirmation dialog in which you select between falling back to the license key entered previously (for the case of releasing a floating license and reverting to the individual license entered previously in the Register dialog) and removing your license key from your user account of the computer.
