How do I get my PC to recognize my camcorder?

I have two camcorders, a Canon HF S11 and a Canon HF S10. The S11 is brand new and came in the box with all the Pixela and Canon CameraWindow software, which has been duly installed. The S10 is a used camera and came with no software. When I installed the software, it asked for the serial number for a camera, and I entered the one for the S11.

My PC (Windows XP Pro SP3) recognizes the S11 for what it is, yet “recognizes” the S10 only as a “Removable Disk”.

Is the fact that I didn’t enter the serial number for the S10 the reason why this is happening? There was only room for one number.

In any case, what do I need to do to have the computer recognize the older camcorder as a camcorder, or be able to get any footage from the S10 onto my PC?
