pgAdmin Slony Creation Scripts

I have installed pgAdmin 1.18.1 but whenever I am trying to create a new cluster using Slony-I, it is always saying that it is missing some scripts. I have copied some .sql scripts from my Slony folder in linux to my pgAdmin folder in windows and set the options file for this folder. However, the problem remains. Does anyone have a solution for this? perhaps anyone can share the scripts please ? I am using PostgreSQL 9.3 on Ubuntu 12.04 and pgAdmin on windows.
