Sorry have still the same problem.
I deinstalled all and install everything again.
Nvidia Driver
Cuda driver
Cudatoolkit
Octane render Demo

and i get allways the error no cuda capable devices found, exiting....

My question is how I install Octane Demo on a PC with a Geforce 8600 GS windows 7 or is the Geforce 8600 not suportet for cuda 3.0?
I tried to install but it dosent work. i istalled Cuda 3.0 + toolkit + octane Demo.
But i get allways the massage that no cuda 3.0 file can be found.

And the same ...
