Hello Badal, we don't support the Boss Cart 1.6, but the new JV series, you may check the demo script
here. If your hosting provider supports the mod_rewrite apache modul please send me your ftp login/user name, phpmyadmin url/ login name / password and the desired URL via emai (bagi(at)bosscart.com, and i will install you as soon as it is possible.
Thanks!
