1AVStreamer uses automatic activation which means you won't have to receive or type registration numbers.

When you purchase 1AVStreamer, it will automatically activate your license.

If, for some unexpected reason your license becomes invalid, 1AVStreamer will provide you automatically with a re-activation dialog in which you will have to type in your original order information and click for on-line re-validation, if the order information matches your license will be valid again.

Of course, you can always get personal support to solve license issues. Read the end user license agreement for all the information regarding purchased licenses.

The registration system 1AVStreamer uses was designed for user satisfaction.
