I am having problems with the call to viEnableEvent - it returns VI_ERROR_INV_SETUP.  This happens from both my code and from the VISA Interactive Control App.
Since this is the first interrupt call I make, I assume the problem must be in my inf file - which was generated by the wizard thus I am at a loss.  I have included the registry keys below. The only other thing that caught me eye is that in this particular machine, there are more that 16 IRQs - and this card is assigned to 17.  I am not sure how common that is now, but I thought I would mention it.
Thanks.
