In Kicad Eeschema, if I try to use the Tools >> Simulator menu entry, I get an error in a pop-up window that libngspice cannot be found, and then the whole Kicad application closes. I see that libngspice is a dependency of kicad so I'm not quite sure what is wrong.

I asked at #kicad at they said that Kicad does not have any gui-adjustable path settings for ngspice or libngspice, so I don't think I have the application configured wrong.

Thank you,

Christopher Howard
