Looks like PrestaShop can’t make the cookie key. Try giving full permission to the folder and run the install again.

This error usually means the installer cannot write the config file. Check if the /config and /var folders have write permission. Set them to 755 or 775 depending on your server. Also confirm that your host allows the PHP openssl extension, since PrestaShop uses it to create the cookie key. After you apply the changes, run the installer again. If it still fails, clear the install folder and start fresh.
