The app you installed goes to your own pc (start/programs/Ray Desktop) on a windows pc. From there you run the "Create downloadable" following their instructions with the proper params to make the app which goes to the programs/Agent folder. Now for others (including yourself) you run the desktop agent to install the actual app you will be using. This is what others will download after you upload to your server. That should get you somewhere . There are some fine tuning setting in the Admin see more plugins Ray base you will need to fill in also for mail video and chat to work properly.

Hope that helps!
