I downloaded the software and installed it with no problems. Runs nicely. The icons initially appear a bit fuzzy but as soon as you move the page, the are sharp again.
I haven't registered my Sony yet with it as I'm not sure whether you need your adobe password and in any case I generally use Calibre.
It was interesting to see when your read a book in the new software that you get a few more magnification levels than appear on the reader (PRS505).
As far as I can tell it seems to work quite nicely.
