I've just installed the latest XAMPP (1.7.4 - previously used 1.7.3) and now the apache server won't start. I did netstat -anobv and found that the process ekrn.exe is using port 80 (xx.xxx.xxx.xxx:80). The problem I have is that it is a mandatory service that cannot be stopped. I tried disabling all protection on my anti-virus but apache still doesn't want to start. Is there a resolution to this that anyone is aware of?
