OK - here are my results. When I run a test and print results (pair selected of course), I do not get any error messages. The viewer does not launch (no indication of error) and the script editor opens with presumably the data we want to see graphically. No error messages when this occurs.

When I click on Zview in the program directory, I get the following message (Same as TankWolf:

C:\Program Files\Zorro\Zview.exe
This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix the problem.

Also running Win XP.

PS - can I get a version of this that runs on Ubuntu???
