ActiveX component can't create object (MATLAB Compiler) - matlab

Question

I know there are similar questions out there, but this one is a little different (I think).
I used the MATLAB Compiler to convert a .m to an Excel add-in. When I run the add-in on my machine, it works just fine. When I send it to a colleague, they get the "ActiveX component can't create object" error. They have added the add-in no problem.
Is there something going on here that's easily fixed?
MATLAB code:
function mess = createAndRouteOrderWithStyle()
c = startbbrg();
[num,text] = exportToM();
s = emsx('//blp/emapisvc_beta');
order.EMSX_ORDER_TYPE = text(1);
order.EMSX_SIDE = text(2);
order.EMSX_TICKER = text(3);
order.EMSX_AMOUNT = int32(num(1));
%order.EMSX_LIMIT_PRICE = num(2);
order.EMSX_BROKER = text(4);
order.EMSX_HAND_INSTRUCTION = text(5);
order.EMSX_TIF = text(6);
events = createOrderAndRoute(s,order);
mess = events.ERROR_MESSAGE;
close(s);
end
Excel VBA code:
Sub GO()
Cells(10,10).Formula = "=createAndRouteOrderWithStyle()"
End Sub
