Time lapse Photography software?

I already tried using EOS Utility (doesnt work because I have 64 bit) and I have tried time-lapse (doesnt work either, many, many errors) does anyone know abotu some freeware that I can use to create a timelapse video by hooking up my camera to my computer? I have tried EVERYTHING and want to get a time-lapse video going, and I prefer to use the computer instead of an intervalometer.
