older version still available online
The older (working) version (v4.03) is still available online. I found it fairly easily with google, but here's the link:
If that doesn't work, it's currently the third hit if you do a google search for "samsung pc share manager".
I installed it and it worked great for my TV and my Yamaha receiver, but my Sony BDP-S570 didn't recognize (couldn't find) the server. So I disabled the Samsung server and installed Serviio, which works amazingly well.
