Some confuion may be developing in this thread. I can run the original version of the plugin (came with the printer last July) on Vista Ultimate. The Garo programs do not work well. I would like to upgrade the driver, the firmware, the garo software and the plugin software which Canon Posted a couple of days ago. However I am concerned that once I get the Firmware snapped in place it will not work with vista and there may be no way of removing it. That could end all printing until Canon posts Vista ready upgrades, whenever. Therefore I am asking whether anyone knows whether the latest versions of the firmware as well as the new driver and Plugin update will run on the Vista platform. I am not having major problems using the original software and firmware which came with the Printer last July, so I am willing to wait if necessary. However if all of the new updates do work I would like to try them. Any thoughts, or experience which is germain???
