Vista and PHP

Hi
My name is Flavio and I have a problem to start Apache; I have installed EasyPhp on my Pc, which uses Vista 64 bit: when I start up Apache a window tell me "Another service uses the same gate". 
I have introduced in httpd file all these IP addresses with different gates  but with no good result:

 
Listen 12.34.56.78:80
Listen 127.0.0.1:80
Listen 12.34.56.78:8000
Listen 127.0.0.1:8000
Listen 12.34.56.78:443
Listen 127.0.0.1:443
Listen 192.0.2.5:8000
Listen 192.0.2.1:80
Listen 192.0.2.5:80
Listen 192.0.2.1:443
Listen 192.0.2.5:443
Listen 192.0.2.1:80
listen 192.168.0.1:80

 

Please can you help me setting my pc. Thank you.
Bye.
Flavio
