Hey Prasanth, agreement: I've actually encountered the same error on my win PC (win7 32bit) note: I assume this is something to do with multiple executables/batch files with same name or something of that sort. since after running a couple of commands anything i'd input would bring me the same "No Perl script found in input" error. solution: After reading this post i've tried something simple - write all commands with ppm.bat instead of ppm. Voila! It fixed all those No Perl script found in input messages Pavel
