This is a technical forum and not the best place to get help about licensing.
I don't really have that much to add to what the AI says. The best approach is probably to contact your reseller.
As the AI says, you may find a license key in the installation media, and this license key may work (I have not tested myself), but while that may work technically, it is more important that it works legally. That is, you need to make sure that you actually possess a license. Else things can get rough if you get license-audited.
