pip install pywin32 didn't work for me but pypiwin32 did.

1. Start a command line with admin rights.

2. python -m pip install pywin32

3. C:\Program Files\Stackless36\Scripts>python pywin32_postinstall.py -install The path C:\Program Files\Stackless36\ should be replaced with the path at which your Python version is installed.

4. Test (admin rights optional) using python -c "import win32com" or python speak.py

   where speak.py consists of this text:

   import win32com.client
   
   speaker = win32com.client.Dispatch("SAPI.SpVoice")
   speaker.Speak("It works. Hoorah!")

You are using pip version 9.0.3, however version 10.0.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

Yes, win32com.client comes with PyWin32. You can install with pip if you have it, via command line: pip install pypiwin32, or python -m pip install pypiwin32. If you don't have pip installed, you can download and install the client from this site.

Once that's running, Idrisi should open up in the foreground when you call it, as per your example. As your script hits calls to different modules, they'll run in that window/session of Idrisi. One note, some of the functions are a bit tricky with the API (the input parameters need blanks as ''), but through trial and error I've been able to get what I needed to work.

the below plus add pywin32 in PyCharm setting work for me

python -m pip install pywin32
