thanks for all the replies. i got both picmulticalc, 1.0.0 and 1.3.1 , and i still get the same missing file error. im thinking that it has something to do with the windows 7 version that im using. (upgraded from winxp running on an old computer)

i have a winxp notebook that runs the calc perfectly, so im using that for now. thanks for the help.

mr mackrackit, yes, the stepper project was interesting. i should have named it "hardware pwm stepper drive" . however, i did not put alot of r&d on that project because of two reasons: i moved on to servo dc motor control, and i use the sla 7078 stepper driver for all my stepper interfacing. hopefully, someone improves it to something practical.
