HOW TO LICENSE
just:live pro 2025 introduces the online license activation process to ease the deployment and license transfer.
One of the biggest benefits of this new online license activation method is its flexibility for multi-location companies. Whether operating across different offices, production sites, or live event locations worldwide, organizations can dynamically allocate their recording licenses as needed, ensuring optimal utilization of resources. Additionally, in the event of unexpected hardware failure, a license can be quickly reassigned to a replacement system, minimizing downtime and keeping critical workflows running—without the need for external support or manual intervention.
With this addition, just:live pro 2025 empowers broadcast production professionals with a modern, hassle-free licensing solution that keeps operations agile, secure, and always ready for the next challenge. The process is straightforward, requiring just an internet connection and a valid license key upon the first activation.
just:live pro 2025 is always fully featured but is not activated by default, and therefore a ToolOnAir generated watermark will be added to all Recordings. As soon as you purchase a just:play pro 2025 licence, you will receive an activation code to remove the watermark.
Please note that an activation is not required to test the just:live pro 2025 solution.
Should you need to transfer your license to another machine, then click on the “Deactivate” button. This will release the license for the hardware and allow the license transfer to another machine.
