When using a user license, GeoT*SOL maintains a license session on the license server. For the duration of a license session, the user license is bound to the respective device and cannot be used on any other device (see Usage on multiple devices).

There are two different operating modes for the license session:

• Online mode: The online license session begins when the program is started and ends when it is closed. In online mode, an internet connection is required, both for starting and while using the program.
• Offline mode: The duration of an offline license session is set manually. The license is bound to the respective device for the entire duration of the offline license session, even if the program is closed. In offline mode, an internet connection is not required, neither to start nor while using the program.

To change the operating mode, open the License information dialog via the menu Help > Licensing and click the button .

• After successful renewal, the license session is valid for another 15 minutes
• When you close the program, the license session on the license server is ended

After closing the program, the license can be used on another device.

If the internet connection is interrupted

If the internet connection is interrupted, the license session cannot be renewed and expires after 15 minutes. Before the license session expires, you will be informed about the upcoming expiry with a corresponding dialog.

Once the internet connection is restored, the online license session will be renewed and the restrictions will be lifted.
