I've had said software on my laptop for a couple of months, but all of a sudden it has disappeared - literally. The icon on my desktop is gone and I can't find any evidence of it ever having existed on my computer. Furthermore, when I go to the Google Earth website and try to re-download it, everything seems to go fine - there are no error messages - but there's still no Google Earth available when it's finished installing. Is this some hidden line in the terms and conditions I missed (product will uninstall itself after 'x', unless you pay us to keep it - kinda thing) or some sort of bizarre virus that just selects a particular application and removes all evidence from your PC... ....or what????
