I\'ve just installed xampp-win32-5.5.30 and in xampp control panel both Apache and mysql started without any error but I found:
1)localhost
To solve this problem in windows I have edited two files.
/Windows/System32/drivers/etc/hosts
Add a line at the bottom like:
localhost sitename.local
/xampp/apache/conf/extra/httpd-vhosts.conf
Add at the bottom:
DocumentRoot "C:/xampp/apps/magento/htdocs"
ServerName sitename.local
You may need to change the above to use your correct IP address (localhost), port number, and document root path. Then you will access the site in your browser by typing in sitename.local or whatever you changed it to.
