What's with my Canon scangear 7.0 not actually doing anything?

This might sound stupid, but I think something is amiss. I have a canon canoscan lide 20 scanner (usb) on my mac mini running leopard. I installed the file in the applications folder, but when i click on it, leopard doesn't know how to handle the file. I also can't find anything in iphoto to set up the scanner. I am an ex-windows user as well, maybe this is contributing. How do I scan something?? It used to be simple on my crappy windows machine. Either that or I am totally missing the point.

You have to download both the Canoscan Tool box and the driver, it's two separate downloads and two separate installs. I have the Canon ide50, works very well in Leopard.

I downloaded BOTH but they are the same file and do the same exact thing. This might be an error with canon's website. Also I open image capture and it says nothing applicable is attached - well, my scanner is attached, so...
