CUDA Nbody.exe file runtime error 13 using cuda 11.3

Accelerated Computing CUDA CUDA Setup and Installation

I have an NVIDIA GeForce GTX 670 and I just upgraded to cuda_11.3. Here’s the version info:

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2021 NVIDIA Corporation
Built on Sun_Mar_21_19:24:09_Pacific_Daylight_Time_2021
Cuda compilation tools, release 11.3, V11.3.58
Build cuda_11.3.r11.3/compiler.29745058_0

When I try and run nbody.exe I get the following output and error:

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.3\extras\demo_suite>nbody.exe

Run "nbody -benchmark [-numbodies=<numBodies>]" to measure performance.

How do I fix this error?
thanks.

P.S. I also get (different) errors when I try and run: oceanFFT, randomFog and VectorAdd.
