the idea is to recommend an application for the user, for example:
if the user click on this link http://earth.google.com/gallery/kml_entry.html#tBiography%20of%20Bob%20Marley
it will open a windows - "open with"
now if Google Earth is already installed the user will click OK as usual
but if Google Earth is not installed the user will get message in the "open with" box "install Google Earth", if the user click OK the pack message will install and run the link with Google Earth.
the same with other links and files
