SOLVED - I can't see the development screensaver

I'm making some modifications to my IP Camera Viewer application and wanting to make sure that the screensaver still works with the modifications I made, I see that the screensaver doesn't appear in the installed screensavers. Only if I install the published application from the channel store I can see the screensaver. What could it be? 

By the way, even if I install the screensaver examples from Roku, I still can't see them in the screensaver list. 

SOLVED: I had some old screensaver installed (Picasa) and after deleting that one, my dev screensaver apearred. Not sure what was the problem, but it's fixed now.
