jupyter notebooks kernel runs correctly

After installation with the requirements.yml file for the API and manually installing jupyter notebook in the environment I ran the first tutorial notebook but its kernel fails as shown below.

Traceback (most recent call last):

Start with requirements.yml and the first tutorial notebook, then reproduce the kernel startup failure on Windows. Investigate the traceback's missing win32api dependency and verify that the notebook kernel starts successfully in the documented environment.
