When will NIS 21.1.0.18 finally be made compatible with Win. 8.1/IE 11?

Norton, you owe your loyal customers an explaniation - are you working on making NIS compatible with Windows 8.1/IE 11 or not? 

 

Not responding to your customers is far worse (unacceptable, actually) than keeping us updated. 

 

Is this too much to ask?
