Pyinstaller ImportError : DLL load failed while importing win32gui

The program works fine including the win32gui calls but the executable gives this error 

  File "Client.py", line 1, in <module>
ImportError: DLL load failed while importing win32gui: Le module spécifié est introuvable.
[4628] Failed to execute script Client```

I am running on : 
Win 10 
Python 3.8
Solution

  • Problem was hidden imports

    So if someone has the same problem you need to add the missing module when building the executable as follows:

    pyinstaller pathToYourPythonFile/script.py --onefile --hidden-import theMissingModule

    For my case the missing module was win32gui. After fixing it, it was another one: screenshot_every from d3dshot library

    So basically you will face this problem if it was a sub import aka :

    from d3dshot import screenshot_every

    so screenshot_every is the hidden import ( you will need to do this to reduce the .exe size )
