Start up the Six Updater (shortcut should be on your desktop) In the Top Left of the window that opens is a large Button with the text "Install or Update Mods, and Launch Game" Choose a DayZ server with 1.7.2 (from the list in the middle) Then click the button mentioned above.

I have tried on 3-4 servers - I only ever got to the "Waiting for Character to Create" screen. I assume the update has some server work that is still on-going. If you can get to that stage then I wouldn't go messing about with your install. Personally I am waiting....... Avast!
