I just downloaded and installed the new "live" client.
Sadly there is a big problem the beta installer didn't have. When i changed the install directory (I don't use C: drive for applications), regardless of which directory I chose or entered in the directory selection screen, the installer always added a "RIFT game" subdirectory.

This is annoying, I wanted to install the game in the same dir as the beta - namely d:\games\rift - and simply could not.
This is a bit annoying as I have a dual boot machine and I have set up shortcuts on both OSes (i'm just lazy to change them) and also because I halways had problems with directory containing the space.

Anyway, now it's installed.
