The error screen is a Moodle error screen ... so, believe it or not, you are getting to that computer (and I am assuming you used a private IP address in the other computers browser).
Think it's saying that the package is mis-configured ... it installs automatically for http://localhost:8080 did it not? localhost on any computer on the internet translates to IP 127.0.0.1 - the loopback IP. (itself)
To make this work from another computer, you have to use the IP address of the machine where moodle is installed. Edit config.php in moodle code and change http://localhost:port to http://IPaddress:port.
Edit that file with NotePad.
Then try and access from another computer on your network by IP address.
Since I don't run Windows nor the package, there is also potential that the web service you might have as an option to choose on startup ... nginx or apache. ... has also been configured to launch using localhost. So when you launch, does it show the
URL to access it?
Also, that IP address is not static ... more than likely your computers get their local lan IP address from a DHCP server and there is not only a lease on that IP but also a range of private IP's s that can be used. Typical home networks are configured to use 192.168.0.x or 192.168.1.z.
Now if you are donig this at your office, might be a different story - different network.
