System ID (find with vba?)

Is there a way to find client’s System ID (for example if their key is still valid and I want to send them a fresher longer term key but they have multiple computers).

Do you have the vba to find the System ID ?

(or even a Excel QAT icon, or menu item would be fine, or I could add to a msgbox)

Thanks…

Sure, it’s explained in the user guide:

Perfect… thanks much
