Microsoft isolating users with Visual Earth

Come on. Microsoft finally had taken in some Firefox users. Or did they?
In the latest try to look at Microsoft Visual Earth’s 3D mapping, we found that you cannot launch the install link on Live Search in Firefox. You are prompted to use Internet Explorer 6 or Internet Explorer 7.
No problem. Booting up Internet Explorer. Click the link again for Microsoft Visual Earth. You save a file called “setup.exe”. Great, you can store it for later. Or can you? When you try to save the 3D maps file, it’s also called “setup.exe”. [sigh]
Can anyone ping the Live team please? Get them to compile it in a different naming scheme. Please? Hello? Is this mic on?
