Can't Export Selected to SVG in v7?

Hi to all,

When I try to export selected to SVG I received this text:

This dialogue requires the RDK to be loaded.

What should I do?

Thank you in advance

PS: In the Properties/Plug-Ins the Export SVG have labels Loaded and Enabled.

Hello - please open Options > Plug-ins page and make sure the Render Development Kit plug-ins are enabled and loaded:
