Are you installing it on a new machine. One that has never had SQL installed? If so, you can't. You need an activation code. People used to make a big deal about that. Me as well. If you email AC, support will send you one as soon as they get your email. If you can't get it, let me know. I will make sure you get it.
If it is the case that you are upgrading to a new machine, you want to alert support in advance.
