I've no problems with uninstalling deskscapes 10 as part of the upgrade process, the issue is that there is no indication that you need to do this when you click the update button in object desktop mgr! - it just downloads the update, attempts to install it, issues a msg saying it's installed deskscapes 11, then returns back to the same screen with deskscapes 11 listed as update... what it should do is uninstall 10, request you reboot and then resume the install of 11, silently failing with no meaningful error msg is pretty useless.
