HOW TO INSTALL NOPCOMMERCE ON PLESK PANEL?

help.softsyshosting.com

mydomain.com - gives 403 forbidden
mydomain.com/install - gives 404 Page not Found

It is as if the document root: website home directory is incorrect.. defaults to httpdocs

What should the root be? Or are there further steps that are needed.

Thanks in advance
