I don’t suppose anyone knows how to correct the IE8/Google earth proxy issue. I lost my google earth when I upgraded and haven’t been able to use it since.
Those pesky IE upgrades!
There is, I might point out, Firefox as an alternative.
To uninstall you have to do it with a command prompt.
If you want to uninstall go to MS's site and search IE 8 uninstall and you'll find the command line. It's rather long so copy paste.
For me, IE 8 sucked.
