Apache Friends Support Forum

Hi,

it's my first time using Xampp and I have problem with starting Apache. I have started MySQL and Tomcat without problems but when I try to start Apache I got the following error message:

08:46:56 [Apache] Error: Apache shutdown unexpectedly.
08:46:56 [Apache] This may be due to a blocked port, missing dependencies,
08:46:56 [Apache] improper privileges, a crash, or a shutdown by another method.
08:52:38 [Apache] Problem detected!
08:52:38 [Apache] Port 80 in use by "Unable to open process" with PID 4!
08:52:38 [Apache] Apache WILL NOT start without the configured ports free!
08:52:38 [Apache] You need to uninstall/disable/reconfigure the blocking application
08:52:38 [Apache] or reconfigure Apache and the Control Panel to listen on a different port

Where I can find the application that is blocking Port 80? I checked logs and they are empty.

I would appreciate your help.

Do you have Skype in your machine?
The problem with SKYPE is that it also uses port 80 and 443.
try changing the port used by skype to 8080 in connection options menu
in skype.

Let me know what happened.

Regards

Skype won't use system pid 4.
