To allow your customers use Miva e-commerce solutions, you need to install on the server the Miva Empresa package shipped with Plesk distribution (if you did not install it during installation of Plesk), and then enable support for Miva applications for the respective hosting accounts.
The Miva Fasttrack and Miva Merchant online store applications are shipped with Plesk as standard Web applications, which you or your customers can install from the control panel's Application Vault section (Domains > domain name > Application Vault > Add New Application). Note that your customers will need to obtain a license either from Miva or from Parallels and specify its serial number during installation of Miva applications.
