Clone the computer before entering the Activation Code. Actually I would do it before installing eLCC application. You wild need unique Soft-eLicenser Number. If you would clone the computer work existing eLCC already, you would need to install the eLCC Helper to every computer manually, to generate the unique Soft-eLicenser Number and then enter the Activation Code.
So install just Cubase. Make sure, eLCC is not installed with Cubase. Then Cline the computer. Then install eLCC to every single computer and enter the Activation Code manually.
