I have used Google Earth for years, but all of a sudden it wouldn't load. The only thing that had changed on my computer was my firewall - I went from Comodo to Zone Alarm. I tried turning off Zone Alarm, but still no Google Earth. So I tried uninstalling and reinstalling, but the download wouldn't install - just said "installing" but nothing happened. I let it go for about fifteen minutes, but nothing. I tried again with both my firewall and my anti-virus (AdAware) turned off, but again nothing. I have a Dell 560 Inspiron, 6GB memory, Windows 7 Home Premium Service Pack 1 64-bit. I have Time-Warner Cable and am using both Firefox and Google Chrome as broiwsers. Any ideas?
