Hi Anne,
That was an add-in I had created...I have kept this one running over the years (IVD performance ) but not the one with the AUC confidence intervals. Now I tend to use bootstrap CI in JMP Pro. Without pro you could build your self a calculator table using column formulas to calculate your interval - there is more than one way to get at the confidence intervals so you would need to decide on the method.
This add-in has the AUC and more (Threshold Explorer).
However that may be more than what you need and can be slow to run.
