Once you've downloaded the installer, just double-click it and have it install to the same directory where you installed the first time.  You'll have two files to download - the base installer and the content installer.  You'll need both.

Just in case you aren't, you'll need to create an account at DAZ.  It's free and simple and will allow you to get the notices of the D|S upgrades and such.
