Multi-touch trackpad in Windows 7?

Ok, so I know that there is not a driver for windows 7 yet with the trackpad. But Windows 7 is built upon Vista so the drivers should work with no problems. The only thing is that when I try to install the driver it tells me that "This update is not intended for this computer and will not be installed". Ok... I get that, but is there a way to decompress the .exe to extract the drivers? Then I could just use the add new hardware feature and install them manually. I am really getting tired of using two finger clicks to right click.
