title: Tensorflow Warning - Insufficient Privileges: 'cupti64_101.dll'; dlerror: cupti64_101.dll
body: <p>Running Tensorflow 2, Cuda 10.1 on Python 3.8
  Dual GPU setup. GPUs recognised by tf2, then initally had error could not find cupti64_101.dll (a CUDA library)</p>
  <p>After copying cupti64_101.dll into libx64 (this solution from another's question), Tensorflow can now see cupti64_101.dll, but I now receive different errors:</p>

  </code></pre>
  <p>I changed the permissions on the cupti64_101.dll to give full permission for all applications. But still get these errors.
  What permission(s) are required on what file(s) to resolve these error messages please?</p>
