"renderer not found error"

[giannis196]

I wanted to render my model but i had the following error report:
"renderer C:/program files/kerkithea rendering system/kerkithea.exe not found:(error,"

Should i install 1 by 1 the renderers?
How to do that?
What is the best (most professional) renderer for wings 3D?

So, how to fix the problem?


I have got OS "Ubuntu 14.04"
CPU 6 core 3.3 GHz
4 GB ram (clock rate at 1333 MHz)
