Cannot get to the "Zen cart set-up Welcome" page

PHP Warning: require(includes/boxes/gv_admin_dhtml.php) [function.require]: failed to open stream: No such file or directory in E:\USERS########dean\www\westafricanmovie\admin\includes\header_navigation.php on line 26 PHP Warning: require(includes/boxes/gv_admin_dhtml.php) [function.require]: failed to open stream: No such file or directory in E:\USERS########dean\www\westafricanmovie\admin\includes\header_navigation.php on line 26 PHP Fatal error: require() [function.require]: Failed opening required 'includes/boxes/gv_admin_dhtml.php' (include_path='.;c:\php5') in E:\USERS########dean\www\westafricanmovie\admin\includes\header_navigation.php on line 26

The error is a bad php file...

If you unpick the error message it is saying that while reading this file:

header_navigation.php

it was asked to pick something up from this file:

(admin/)includes/boxes/gv_admin_dhtml.php

... but could not do so.

If you send (via FTP) a FRESH copy of:-

admin/includes/boxes/gv_admin_dhtml.php

to the identical directory on the remote server, it may repair the problem.

Genius! Thank you

I have been going by the book and cannot reach the "Zen cart Set-up Welcome" page.
I have down loaded the latest version of Zen cart even though the book is using a older version.

I am trying for the first time to install Zen Cart and using the book called "e-start your web store with Zen Cart".
I can not get to the step where you see "Zen Cart Set-UP Welcome" page.

Are you installing on a live host or your PC?

On my PC

According to the book I should be able to get the the Set up page
by typing the url: https://www.example.com/store but it goes to the page.

Welcome to XAMPP for Windows Version 1.4.16

What happens if you type http://localhost/store?

In addition, have you made sure that your Zen Cart files exist under something like "C:\xampp\htdocs\store" as per the screen shot on pg 46?
