error while executing "apache services"

i am trying to install apache version 2.2.16, on my windows 7 machine. the apache is installed correctly. but when i try to run the service, i get a error message saying, "The开发者_开发技巧 requested operation has failed"... i tried all the methods, i.e disable antivirus, skype, but still the same result.

Are you runnin IIS on the same machine? By default, they will try to bind to the same port 80), and if IIS is running on bootup, then Apache will not be able to start. Try disabling IIS on startup, or else change the port that one or the other uses.
