#12 Render aborts with Error Message

[Jürgen Werner]

Using PovClipse 1.0.1, Eclipse Indigo 3.7.2, OS Win8.1 64bit, Java 7

When I try to render the Projects scene, Povray starts and ends with error:
Failed to start render: Failed to write output INI File.

I do not see any error within eclipse, and the output window of povray does not explain more. I don't have any idea what File it tries to write where... and it does not say why the INI file cannot be written.

The Configuration is checked many times and seems to be ok.
