My Client Ver. 0.1.19 Dragonica (SEA)
Windows Vista
It works just fine for me.
It took me a moment at first to get it to work ...
I had to "Run as Administrator" (Vista Right-Click Command) and it worked fine.
Run it before the game, then after it's open launch the
game. If it disappears when you click start in the patch,
that means it is working.

Edit: I also placed it in the Dragonica folder ... I don't know
if that helped it at all, but eh ... worth a shot.
Time for me to go back to killing.
