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.
