for some reason, it works and then it doesn't work. Today July 1st 2013, I uninstalled it and reinstalled WAMP, still not working. Yes I did uninstall it. Icon is Green and online. dyn.com is registered with my current ip address, port forwarding is is turned on my Linksys router, Application & Gamming/ Port Forwarding: "Wamp Server " / 80 to 80 / Protocol: both / to IP Address 192.168.1.104 / Enabled x.
Wamp / Appachee / Services / Test Port 80 ==> Your port 80 is actually used by: Server: Apache/2.4.4 (Win64) PHP/5.4.12
ipconfig/all // IP routing Enabled: NO // WINS Proxy Enabled: NO
IPv4 address: 192.168.1.104(prefered)
Some people say windows works with IPv6 address: 2001:0:9d38:6ab8:2c6f:2192:9eb1:d16f

It has worked with windows xp and vista just fine.
