You wouldn’t be able to “upgrade” to C6 from the C5 demo because you hadn’t paid for either yet. I imagine you would have to buy C5 outright before you can “upgrade” to C6 or buy C6 full version. You can upgrade to C6 from a previous paid version. Don’t know why you would upgrade to C5 at this point unless you’re worried about not being supported by SB on an OS previous to W7.
