I had the same issue. Here is what I did
installed
`conda install -y plotly plotly-orca’
from windows powershell and it worked without errors.
I found the orca .exe installed in the path:
C:\Users\jwa2044.julia\conda\3\orca_app
Set the user environment variable to include this in the path
Then did
build “ORCA” in the julia pkg prompt
It worked.
Then the compilation went smoothly.
