Apache server won't start?

I just recently installed Apache Server and I can't get it to start. I've googled the error messages and tried following the suggestions and it still won't work. I have attached the message. What am I doing wrong?

Thanks,

Your localhost may not be setup, you can check by opening your hosts file which normally live here - C:\Windows\System32\drivers\etc\ and search for a line that reads - “# 127.0.0.1 localhost“

If you have that line then delete the # and save it, if you dont have that line for some reason, add it without the #

then restart Apache see if that fixes it ?
