[H] vista 64 and Google earth

[Winterlight]

I am not able to install Google earth on my new build of Vista 64. 
It  is a quadcore with 8GB of RAM and a 4970 video with raptor hard 
drive so performance isn't the issue. If I try to install on line it 
just fails, and if I download and attempt to run setup it won't even 
start up... anybody know why.. it is suppose to be supported?

thanks
