I installed WAMP Server. When I click on start WampServer a Pop up window came up, said: "Aestan Tray Menu has encountered a problem and needs to close. We are sorry for the inconvenience. if you were in the middle of something, the information you were working on might be lost"
I have read that the reason can be Skype as it could use the same port, but I uncheck "use port 80 and 443 as alternatives for incoming connections" but the problem still exists.
I installed the right version of WAMP(32 bit ). Port 80 is open.
