I successfully downloaded moble google earth and it was working fine. Did the upgrade to .75 and now I can't find it. I have even tried downloading it again, but i get a message saying it already exists. I select "yes" to replace and then it reboots, but still doesn't appear. It doesn't appear in downloads, applications, anywhere on the desktop.
If you can absolutly not find it try going in to Options>Advanced Options>Applications. from there delete google earth and download again... should go to the downloads folder since it wont be replacing an old one.
