CUDA Running error Compiles fine but doesn't run

I seem to be having a problem running the convolutionFFT2D example. The code compiles fine but when I run it I get the following error.

Error: API mismatch: the NVIDIA kernel module has version 169.04,
but this NVIDIA driver component has version 100.14.11. Please make
sure that the kernel module and all NVIDIA driver components
have the same version.
There is no device supporting CUDA.

I am relatively new to linux and hope someone could give me a hand.

Thanks in advance

Looks like you didn’t install the CUDA_1.1 toolkit (or remove the older version).
