I thought I was taking the easy way out by using available drivers with all the error handling built in. The setup on some GPIB instruments is not trivial and it's nice to have the examples supplied with the drivers. It still seems somewhat of a toss up to me as to whether I should write my own drivers or live with all the installation hassles. I just don't understand why the installer isn't smart enough to install the run-time version of all the necessary drivers.

Having experience with distributing GPIB applications myself, I have long decided to stick with the basic GPIB Read and Write functions. You don't need VISA for those. Also, IVI is nice to get started but each driver requires an install for the DLL's it needs. You should be able to read the IVI driver code and build a few simple GPIB calls to do what you need. Power supplies have a limited command set. Michael Aivaliotis > I just tried to load an executable I built.
