It seems that the /special/ DLL provided by Moray to communicate with 
POV-Ray, only works with version 3.5. When you have installed POV-Ray 
v3.5 you can see at the top "GUI-Extensions" and within "Moray 
Communications DLL" which is probably installed there I guess, the first 
time you link both apps. Somehow, Moray is unable to link that DLL with 
a more recent version of POV-Ray.

It may be worthwhile to check the directory paths shown in the "Render 
Options" and maybe adapt those to your particular wishes...

I thought so too...

In my case, POV-Ray v3.5 just freezes, and I have to crash-close it...

I am able to uncheck it but I don't know what is its use...

In any case, in most instances, either POV-Ray freezes, Moray cannot 
make contact, or nothing happens. In rare cases, a miracle occurs and a 
render is performed, typically with Moray files younger than about 2000. 
When a render occurs, I am unable to repeat a second render. In any 
case, I am unable to render any scene in POV-Ray v3.5 so there is much 
not working as it should (Windows problems with older apps?)

I am curious to learn your experiences.
