I have a problem with a package of NBU 4.5 for that someone has purchased for us over a year ago and now I am trying to install it. Inside the package there is a slip which has three sticks on it and it is supposed to be the license number. It is similar to NBU's license key format. But when I try to install NBU using this license key which was inside the package, I get a "Invalid Key" message. Is this number indeed the number I have to use for installation? Do I have to obtain some other form of a key using this license number from Veritas. Please let me know your experience.
