newbie: apache doesn"t start after setup

Hello,
I have installed apache_2.2.6-win32-x86-openssl-0.9.8e.msi in Windows XP and
I have a problem. When I start Apache I recive (I translate from Polish
language):

(OS 10048)Only one use of each socket address is allowed. : make_sock: could
not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
Note the errors or messages above, and press the key to exit.

I don't know know what to do.
Command "netstat -n -a" returns:

Protocol Local Address Foreign address Status
TCP 0.0.0.0:80 0.0.0.0:0 LISTENING
TCP 0.0.0.0:135 0.0.0.0:0 LISTENING
TCP 0.0.0.0:445 0.0.0.0:0 LISTENING
...

Please help.

That means you already have a service running on port 80.
Probably IIS or something like that if you're running Windows
