Hello, I am not sure which list this should go to, so apologies if I got the wrong one. I am running Win 7 64 bit I would like to run both the latest stable release and the cvs on the same machine. I have installed both in separate directories. My problem is that gretl 1.9.90 is calling gnuplot from the gretl cvs installation, i.e. "C:\Program Files\gretl_cvs\wgnuplot.exe" "C:\Users\Logan Kelly\AppData\Roaming\gretl\gpttmp.c09324": exit code 1 Instead of "C:\Program Files\gretl\wgnuplot.exe" "C:\Users\Logan Kelly\AppData\Roaming\gretl\gpttmp.c09324": exit code 1 Is there a way to tell gretl where gnuplot is? By the way the error from gnuplot is what has prompted me to do this, but that is another post for when I have a chance to investigate. Logan
