The dongle uses CodeMeter technology. On Windows targets, check the system tray for the CodeMeter Control Center. On Linux, run systemctl status codemeter .

The .lic file is corrupted or for a different CODESYS version. Solution:

The license resides on a physical USB security key. This option allows you to easily move the license between different computers or PLCs by simply unplugging and plugging in the USB drive. Prerequisites Before Activation
