Answer:
With the release of customer version X.20.01, the license drivers of GEMALTO have also been replaced. The update of the GEMALTO drivers closes a safety gap. Therefore, it is necessary to install the new drivers on the server.
Proceed as follows:
- Download the drivers: http://download.dlubal.com/?file=Sentinel_LDK_GUI_setup.zip
- Close the Dlubal Software programs on the clients.
- Install the new drivers on the server.
The server is a computer with the inserted network dongle or activated NET‑SL. The client is a computer on which the DLUBAL programs are running.
Note: The previous program versions can also be used with the new license driver.
