I had the same problem as others with the activation code although I did manage to get it activated.
To activate the software “Don’t enter the activation code in the first box that pops up”, instead select the option in that window at the bottom of that menu “Activation”, a new window will open up and from that screen you’ll need to enter a First & Last name / Email / and at the bottom enter the activation code supplied here by SOS. That’s what worked for me. Hope this helps someone. Happy Holidays!
