No reply from him yet,hmm.Waiting.And thank you

I install the cuda toolkit 3.0 but setup makes the destination folder to c/cuda folder so there was nothing there before,and no overwriting ofcourse in this way,how to overwrite them??

Hehe,how about the driver 258.56 ? I couldn't find any info about it ?

I've installed cuda toolkit 3.0 but don't know where to put those files to.And the file that nvcuda.dll is not exist in the cuda toolkit 3.0 so,that doesn't change my cuda version i think.

You helped me a lot and replied much(didn't work but ,hehe)
Thank you very much.Then we will wait for the what radiance says.

Octane is ok by itself,i just get error when trying to import a mesh,it crahes during the compiling mesh/voxelizing.
Do you have the nvcuda.dll of cuda 3.0,i just deleted the 3,1.

Hi thanks but didn't work,i uninstalled and also used driver sweeper to delete whole drivers but cuda was 3,1 and octane crashed again :(

Ohh,thank you very much,waiting for the link thanks.

I just uninstalled the whole nvidia drivers,now installed the cuda 3,0 but which version of nvidia driver you recommend for me ? O/C is %100 stable.

No no,i had 3,0 but it was crashing anyway so now i updated everything up to date,so ?Any idea?
