It looks to me that it doesn't even find gnuplot.exe
Is this executable in the executable path ?. It must be. 
Otherwise you can specify the full path to the gnuplot_command
in your system (but you will need to do that for each
release)

I do not run windows, but I changed the gnuplot_command to a 
non existent name in my Linux box and I get an error message
somehow similar to yours. 

Best luck,
