According to Microsoft your printer is W7 compatible for both 32 and 64 bit OS. Also the native W7 driver support should provide the basic printer functionality but additional functions are provided by the add-in module.
I suggest you uninstall the add-in and all your printer drivers. Then shut it off. Plug the printer directly to the W7 computer, make sure it has network connectivity, and turn it on. Once the printer driver is installed then install the add-in.
These are the Canon FAQ items regarding the printer & the add-on ...
