can not find install info to setup invoicing and download.php

I can not find install info to setup invoicing and download section for Company WebSite Builder PRO 1.9.8 - shopping cart edition

I have the zip file in the addon directory but do not know where and in what sub directories to install said files the script is installed at http://todaysincome.com I have installed the files to unlock the lite version that I was sent after I bought the script


I also need to edit company info but do not see anyplace in the admin section to set this up

Is a little bit mixed what you write here, can you be more specific?

To edit company Info edit please
