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".
I installed the right version of WAMP(32 bit ).
Everything is unchecked I mean Internet Information Services (IIS)... I checked even which programs are using port 80. Port 80 is open. My OS is XP SP3. The problem still exists.
