ImportError: no module named win32api
This is resolve my case as found on Where to find the win32api module for Python?
pip install pypiwin32
I had an identical problem, which I solved by restarting my Python editor and shell. I had installed pywin32 but the new modules were not picked up until the restarts.
If you've already done that, do a search in your Python installation for win32api and you should find win32api.pyd under ${PYTHON_HOME}\Lib\site-packages\win32.
