mulrunfitter on window

[leora Sarid]

I am trying to use the mulrunfitter on windows. Each time I try to enter the information necessary for the fit I get an error message:

Arg out of range in user function near line
{gensel(hoc_ac__, 0)}

Deck[0].flip_to(4 )
ParmFitnessGui[0].gengui(4 )
ParmFitnessGui[0].gensel(40 , )
Deck[2].map( )
and others

When I use the mulrunfitter on linux I don't get this error
