Access XAMPP from my local network

There was a quite similar Q here years ago, but it's not getting me to where I need to go.

I have XAMPP 5.6.14 with Control Panel v3.2.1 on Windows 7 Enterprise here at work, and I have a demo to do for my boss on Friday.
I need to get this working on his desktop.  The network is open w/in our domain.

I have a fair amount of PHP and javascript in DIRs that I need to have accessed, but with the methods I've tried all I get is the HTML.
(Apparently.)

I modified apache config httpd-xampp.conf file's location match two ways, same result.
A)  I commented it all out, and
B) I commented out "Require local" and inserted (above "ErrorDocument 403 ..."),  "Allow from XX.YYY" where those are my higher bytes.

#
# New XAMPP security concept
#
<LocationMatch "^/(?i:(?:xampp|security|licenses|phpmyadmin|webalizer|server-status|server-info))">
#        Require local
         Allow from XX.YYY
	ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var

</LocationMatch>

Select all Open in new window

I get the raw index.html to show, but no jQuery works to populate the DIVs.

I have the standard XAMPP install w/in C:/ DIR.

Thanks!
