When I attempted to register my newly purchased and installed 3-user Bitdefender Antivirus Plus 2014 in XP, I received the message, "Registration was not completed because this PC is not connected to the Internet ...." This seemed odd because all other Internet accessing programs (e.g., Google Chrome) were functioning fine. An option to complete registration offline was likewise unsuccessful, giving the error message, "The license key you have entered is currently used in the product. You cannot register the product twice with the same key." Reinstalling, repairing and updating coupled with deactivating programs that I thought might monitor the Internet and closing Windows Firewall have not helped. My former AVG antivirus software was uninstalled but possibly might somehow be lurking out of sight.
Anyway, now my registration window explains that after entering my license key, "Registration will be completed when this PC is connected to the Internet." But again I receive the reply that, "The license key you have entered is currently used in the product. You cannot register the product twice with the same key."
Other forum posters have reported the same problem, but as yet there have been no answers. I am a Bitdefender fan and am hoping for a solution. Thank you
