Problem with aBSDF model

Hello,

If I try tu run bsdf2rad I have the message “‘bsdf2rad’ is not recognized as an internal or external command, operable program or batch file’”
I can run bsdf view, and it open a rvu windows, but I have the same message about bsdf2rad :"‘bsdf2rad’ is not recognized as an internal or external command, operable program or batch file’".

Il the radiance folder, I can’t find any file named bsdf2rad… (neither a perl script)
