Hi Chris.
What you need is Canon's 'EOS Utility'. You might also like Digital Photo Professional(DPP).
These come as part of a software suite they call the 'EOS Digital Solution Disk Software' which comes with a CD/DVD disk when you purchase a new camera.
The software is downloadable, for people to update, but some strange person at Canon made a strange decision that you can't use this downloaded software until you insert your original disk to prove you have a Canon camera, even tho the software can only be used by someone with a Canon camera!
There are workarounds but it was so long ago that I did it that I now can't remember them, sorry. I think it may have been a disk image that I got somewhere and then burned to a DVD. I now have an original that came with my 60Da.
Anyway, a bit of sleuthing on Google for the above should get you there eventually.
Good luck
