This message is telling you that Weather Watcher is currently running. You have to close Weather Watcher before you can reinstall it on top of itself.
Right-click the Weather Watcher icon in your system tray and choose “Exit” from the popup menu to close Weather Watcher. If you don’t see the icon in your system tray, then you’ll have to close Weather Watcher from your Task Manager (close the ww.exe process).
