I have bought a new PC and now I want to uninstall the student software on the old one and install it on the new one. But even if I uninstall it on my old computer the installer says I have already used the licence to install it. Does anyone know how to do it? Or isn't it possible at all.

I know it's possible (It worked for me) to install one license to one main computer and the same license to an auxiliary computer (like laptop)

I hate that type of software, because what do you do if you switch computers? Or is there a way to recover the old license then uninstall the first copy?

same here

Thank you, they've sent me a new license number.
