wamp server not working on 8.1

Question

I just upgrade to win8.1 from win8 and I can\'t start wamp server (2.2 x64)

Answer 1

all of your's answers are wrong, not only wampserver but also xampp is not working on windows 8.1 because apache server is not running in windows 8.1 with port 80, becouse port 80 is system reserved port.
