I never got to the point where it gave me options for activation, it rejected the product key and I don't think there was any option to continue installation. Did I miss something there? (I was trying to install with Boot Camp, as I recall it just had an option to enter the product key and hit next, where it told me it was invalid). I had to power down to return to my Mac.
Thanks for any help, I'm trying to figure out if I need to return it or if there's any chance to get a new product key.
