You have to install the whole thing.
It will install as an upgrade.
Build 1415 is still a better version, has alot more
new things, they took alot out for the 1423 release at the
conference and didn't put it back in 1434.
Personaly I am running a 1434/1415 hybrid <g>.
I loaded 1434, then 'upgraded' to 1415 by loading 1415
yet keeping all of the 'newer' drivers installed by 1434.
Doing this has givven me the most stable build yet,
plus the bells and whistles from 1415.
Good luck..
