If you update the eLicenser database on the C9 desktop machine, you can still run C9 on that desktop machine, with the eLicenser with the C 10 license on it. If that was the Question.
Well the question is more about the usb elicensor - i switched completely from the “machine-based” licence (or whatever they call it) to the usb-based licensor which allows to use the software on multiple machines (one at a time, as ling as i move the usb-based licensor to that machine).
My question is: would the usb key keep both C9 and C10 or just C10?
‘cause as far as i remember, once one has made the choice to transfer eLicencer to a USB-based one, it’s not possible to go back…
