If you get the message 'The feature you are trying to use is on a network resource that is unavailable' the cause could be, when you installed Schedule it previously you installed it from a network location, a temporary location that is no longer available, or Windows cached installers are no longer available.
During an restart or upgrade, Windows checks the last installer file to see what has change and also tries to remove older files ready for the new update. If the older installer is no longer available you can see the error above.
: From the Windows Control Panel, remove Schedule it, then download again from our website, chose 'Save As' to save the zip file to your desktop. Once downloaded open the zip and re-install.
: You can use the Microsoft Program Install and Uninstall utility to remove the older Schedule it version and re-install the latest version. Get it here... https://support.microsoft.com/en-gb/mats/program_install_and_uninstall
