Do I want to do that?
Checking things out ... stand by for an answer.
OK ...
I am browsing with Firefox v18.0.1 on Windows XP Pro SP3. I went to http://www.google.com/earth/index.html and hit the “Download Google Earth” button on upper right corner. At the next page, I unchecked the “Include Google Chrome etc.” radio buttons and hit the “Agree and Download” button below the legalese. This downloaded an executable installer. I ran the executable installer and it in turn downloaded and installed Google Earth ... current version appears to be 7.0.2.8415, at least on Windows.
Not sure what the problem might be; perhaps you need to update your browser?
I don’t use Chrome, but it has its fans.
