spent the last 1 1/2 days trying to get up and running with lesson 1. after a bit of work and updating C++, reinstalling all of anaconda (p36), running prompt using admin rights, and manually installing shapely, the conda env update step ran successfully and I followed the rest of instructions.
When I got into jupyter notebook and opened lesson 1 ipynb, I get a “Kernel Dead” message with the following log:

FileNotFoundError: [WinError 2] The system cannot find the file specified
Any idea? I can’t tell from here what is missing?
UPDATE: Thinking tornado needed to be installed I tried conda install -n fastai tornado. This ran successfully, but still receiving same message as before
UPDATE: Removed the fastai environment and going to try conda env update again fresh to see if I missed something along the way…
After the refresh of the fastai conda env, got this warning:
The script plasma_store.exe is installed in 'C:\ProgramData\Anaconda3\envs\fas
tai\Scripts' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warn
ing, use --no-warn-script-location.
The script pbr.exe is installed in 'C:\ProgramData\Anaconda3\envs\fastai\Scrip
ts' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warn
ing, use --no-warn-script-location.
The script kg.exe is installed in 'C:\ProgramData\Anaconda3\envs\fastai\Script
s' which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warn
ing, use --no-warn-script-location.
Added this to system variable PATH, but still same issue with dead kernel after activating fastai, adding link, and running jupyter notebook:
