Jupyter Octave Kernel on Windows7

Question

Followed the instructions at https://github.com/Calysto/octave_kernel to install octave_kernel on a Windows1 machine and everything went ok. However, when I select Octave as my kernal from Jupyter, the following occurs.

The kernel has died, and the automatic restart has failed. It is possible the kernel cannot be restarted. If you are not able to restart the kernel, you will still be able to save the notebook, but running code will no longer work until the notebook is reopened.

I also cannot get oct2py to work.

The Jupyter console output from the octave_kernal attempt follows.

PermissionError: [WinError 5] Access is denied

I saw the permission error and tried to run Jupyter as an administrator to no avail.

Set enviornment variale OCTAVE_EXECUTABLE as C:\Octave\Octave-4.2.1\bin\octave-cli-4.2.1.exe. Provide full R/W permission to user Everyone on Octave install folder
