If you are desperate to get XAMPP up and running, you should consider changing the port from the default 80 to say 7777.

 In the XAMPP Control Panel, click on the Apache – Config button which is located next to the ‘Logs’ button.

 Select ‘Apache (httpd.conf)’ from the drop down. (Notepad should open)

 Do Ctrl+F to find ’80’ and change line Listen 80 to Listen 7777

 Find again and change line ServerName localhost:80 to
ServerName localhost:7777

 Save and re-start Apache. It should be running by now.

The only demerit to this technique is, you have to explicitly include the port number in the localhost url. Rather than http://localhost it becomes http://localhost:7777.
