i have 2 elicenser device.can i use cubase pro 8 education version in 2 computer in a same time?
I’m not sure if i understand your question…
So, what I can say is that if your Cubase license is stored on a USB eLicenser then you can install and run that Cubase on either computer. But, you can only use Cubase on the computer where the USB eLicenser is connected.
If you have 2 USB eLicensers that have a different Cubase license on each one then yes, you can run both both Cubase software on both computers at the same time. You need to make sure that each computer has the version of Cubase on it that applies to the license on the USB eLicenser that is connected to that computer.
