# License Management

License activation requires the computer to be connected to the internet. **One license can be activated on one (and only one) machine at the time.** After a license is activated, the machine no longer needs to be connected to the internet for a certain amount of time (depends on license level, typically 4 weeks). A warning is displayed both on licenses what are soon expiring and on licenses that soon need to be activated online again.

The activation of a license will transfer data uniquely identifying the PC that the software is installed on to Voysys.

Licenses are handled in the **Help** menu. See [Activate licenses](../start/activate-licenses.md) for the step-by-step activation flow.

To transfer a license to another computer first use **Help**  **Revoke current license**. Then use **Help**  **Enter new license key** on another computer.
