After the installation of the software on the computer, the

icon will be presented in the tray icon area.

Note:

When a CmStick is plugged into an USB socket of a LCD monitor, the CmStick will not be detected

by the software protection server if the monitor is switched off.

Warining:

Never try to debug the W-PCI, W-PCIe or W-CODE software. This will disable all the licenses

on the CMStick.

You can find more information regarding the CodeMeter and CmStick in the related help file.
