I am running 32 bit. I did the upgrade from Vista SP1 32 bit. When Windows 7 started, it didn't know what my printer was and when I selected "Manually select model", the iP8500 wasn't there. I did go back to the Canon site and downloaded the Vista add-on
driver, but it didn't help. So, printing works OK, but the status monitor doesn't work (so I can't tell if a cartridge is running low on ink, etc.).
Any thought?
