Hi,
Today i was installing XAMPP on windows 7 desktop. Well, the installation gone perfectly well. Finally, i was able to access XAMPP control panel, but, the moment i started apache 2.2, it failed. Then i installed it as a service and then started, but it was still in vain.
Later on, i changed C:\xampp\apache\conf\httpd.conf file contents as below
Listen 80
to
Listen 81
and then restarted the service, finally it worked.
The reason why i changed the port is because i later on found that skype also listens to the same port which was a default port for Apache 2.2
