Java Error when using compiled matlab code (GUI) using the Instrument Control Toolbox

Hello,
I'm trying to compile and use an EXE of a Matlab GUI that I've written to control a few instruments and run an automated data collection cycle on a long term test. The code works fine as a *.m, however it stops and spits out a java error when I run it compiled. The error comes out thus:
C:\...\exetest>VoltageRamp
C:\...\exetest>Error using instrhwinfo (line 152)
Java exception occurred:

Error in setupPS (line 9)
Error in VoltageRamp>btnStart_Callback (line 422)
Error in gui_mainfcn (line 96)
Error in VoltageRamp (line 43)
Error in @(hObject,eventdata)VoltageRamp('btnStart_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating uicontrol Callback
The code for setupPS looks like this:
function setupPS( ipAdd )
%SETUPPS Summary of this function goes here
% addr = GPIB address of the supply
c=strsplit(num2str(ipAdd),'.');
hware=instrhwinfo;
if ~isempty(find(ismember(hware.SupportedInterfaces,'gpib')))
hware=instrhwinfo('gpib');
end
if ~isempty(find(ismember(hware.InstalledAdaptors,'ni')))
hware=instrhwinfo('gpib','ni');
end
...
That code continues, but error was at line 9 above
Now the only thing else that I find worth even mentioning is that I'm compiling this on a different computer than I'm attempting to run the *.exe on. However that shouldn't matter (afaik), both have exactly the same NI driver sets, both computers have exactly the same version of Java on them. I have not tried simply compiling setupPS to exe and running that, but that seemed a fruitless diagnostic path to me.
Any help would be greatly appreciated.
