OS: Win7 64bit Ultimate. Using the latest install app from Canon
the 1023 installed just fine for network printing. However, when I did the install for the USB connection (to access the scanning function), Windows does not recognize the scanner. It will print via USB, but the Canon scanner software reports no scanner installed. ALso, Device Mgr shows the device with the proper name (1023) but otherwise with a yellow caution mark, and no driver installed.
BTW, this all works just fine in WInXP Pro 32bit. But, I would rather not install the scanner in an XP virtual machine, since both Canon and MS claim the device is Win7 64bit compatible.
BTW, I was using the latest Win7 64bit URFII driver. There are two DLs listed and it is not clear which or both to use, or in what order to install them:
