To install PrestaShop, you need a remote web server or on your computer (MAMP), with access to a database like MySQL. You'll need access to phpMyAdmin to create a database and to indicate the information in the database in the installer.
If you do not host and unable to create your store, we offer a turnkey store, which lets you create your online store in less than 10 minutes without any technical knowledge. We invite you to visit: http://www.prestabox.com
Simply go to your PrestaShop web directory and use installer :-)
If you have any PHP error, perhaps you don't have PHP5 or you need to activate it on your web host. Please go to our forum to find pre-installation settings (PHP 5, htaccess) for certain hosting services (1&1, Free, Lycos, OVH, Infomaniak, Amen, GoDaddy, etc).
