1. Create a database for your store, or use the database designated by your hosting company.
2. Make sure the GD Library is enalbled. On a default installation of PHP, the GD Library should be turned on, but if that's not the case for your install, here is the standard Windows instructions are:
   1. In the root directory of your PHP folder, open the php.ini file.
   2. Uncomment the line extension=php_gd2.dll (about half-way through the file, in the middle of a long list of extensions) by deleting the ;
   3. Restart the PHP services.
3. Download the PrestaShop e-Commerce solution software.
4. Unzip the PrestaShop ZIP archive anywhere on your hard drive.
5. Upload the contents (not the folder itself) of the /prestashop folder to the root directory (e.g., http://www.mysite.com/) of your hosting server via FTP. You can also upload the files to a subdirectory you’ve created (e.g., http://www.mysite.com/prestashop/) if you wish to keep your root homepage separate.
6. While you are connected to your Web hosting FTP server, make sure the following PrestaShop folders have "write" permissions (also known as "CHMOD 775", or "CHMOD 777" depending on your host – you can find an explanation of file permissions here) but do not apply these permissions recursively (ie., to their subfolders): /config, /upload, /download, /tools/smarty/compile. Then, make sure the following folders have "write" permissions: /img, /mails, /modules, /themes/prestashop/lang, /translations
7. In a Web browser, launch the Installer by going to your shop's root address: you will be redirected to the install (e.g., http://www.mysite.com/prestashop/install).
8. Upon completing the PrestaShop Installer wizard, use your FTP software to navigate to your /prestashop folder. There, delete the /install folder and rename the /admin folder (for example, to /admin123 or, even better, /xyz789). This is for security reasons. If later you forget the name you gave the /admin folder, you can confirm its name via your FTP browser.

After you have confirmed that your test version works as it should, copy the test version over the live version. (It is best to do this after peak usage hours, and with your store properly and temporarily disabled from within the PrestaShop back-office.)

Uninstall PrestaShop

PrestaShop is very easy to uninstall:

1. Stop the web server and your database on which PrestaShop is installed, if you can.
2. Delete the /prestaShop (or the name you gave it after the installation, if you renamed it) from the current directory of your Web server (generally 'www').
3. Delete your PrestaShop database, using phpMyAdmin.
