fyi to itinmind: I have the OK, a KW and now the KT and a Windows 7 Pro desktop. I did not need to do an uninstall and reboot of the computer.
www.kobosetup.com nicely replaced the older desktop (I think it was 1.9 but I'm not sure now) and replaced seamlessly with 2.0. No issues, an no extra hoops to go through. Nice job, developers!
