I don’t remember having an activation key I also says with an error message my system has not been modified hell it is a brand new computer with windows 7 what gives

Hi, do you get any error message? There are DEMO mode for 14 days. In this time you need to activate free or commercial license. Why do you think it is a problem with license?
