Updating FIJI offline / through Remote Desktop Connection

Hi there. I was really liking the Automatic updater although using the code:

import ij.IJ;

//System.setProperty(“java.net.useSystemProxies”, “true”);
System.setProperty(“http.proxyHost”, “-----”);
System.setProperty(“http.proxyPort”, “-----”);
IJ.run(“Update…”);

to get around the firewall, but unfortunately our IT department has panicked and stopped internet access to lab workstations. I can RDP through a network to a laptop with internet connection so is it possible to modify the above code to run the Updater through a RDP? Or failing this, are there ways to access updated FIJI files and manually updating? Thanks
