Ok here's what occuring.
I install Weatherbug and it puts it's stuf in a folder called Weatherbug in the Start Menu>All Programs like most intallers do. As long as I leave the Weatherbug folder in the place it put it in (Start Menu>All Programs) it's fine. But, I get this reinstall when I delete the folder with the Weatehrbug stuff.
I prefer to make my own folders for my programs and I would normally move just the Weatherbug executable to anothjer folder and delte the folder it created.
