I just tried installing the unimpressive BitDefender 2012 on my XP x64 SP2 machines. To my surprise, BitDefender has dropped support for XP x64. Thank you. Guess I'll use BitDefender 2011 until my XP no longer functions the way I wish it to function. I have two partitions, one with Windows XP x64 and Windows 7.... prefer XP x64. BitDefender was one of the only security suite providers that supported XP x64, and now they're gone.
Too bad. Would be nice if you brought support back to XP x64 64-bit SP2, but I doubt it will happen.
