Python 3.13.0 : PyWin32 is full compatible with Python 3.13 .

Today I tried to use these python packages:

import win32serviceutil
import win32service
import win32event
import servicemanager

The works , but python -m pywin32_postinstall -install comes with:

python.exe: No module named pywin32_postinstall

NOTE : The copilot artificial intelligence, search and give me an old answer , but is wrong ...

PyWin32 is updated slowly, and at this moment there are no wheels for Python 3.13.

The pip tool cannot install pywin32 does not install anything usable, and pywin32_postinstall does not exist

Possible solutions

PyWin32 works perfectly on:

• Python 3.12
• Python 3.11
• Python 3.10

If you need win32service, win32api, win32com, etc., you must use a supported version.

Need to see the last tutorial from my blogger.

I tested on admin with simple service and works:

python service_test_001.py install
Installing service MyPythonService
Service installed

This is the source code:

import win32serviceutil
import win32service
import win32event
import servicemanager
import time

class MyService(win32serviceutil.ServiceFramework):
    _svc_name_ = "MyPythonService"
    _svc_display_name_ = "My Python Windows Service"
    _svc_description_ = "A minimal Windows service example written in Python."

    def __init__(self, args):
        win32serviceutil.ServiceFramework.__init__(self, args)
        self.stop_event = win32event.CreateEvent(None, 0, 0, None)
        self.running = True

    def SvcStop(self):
        self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
        win32event.SetEvent(self.stop_event)
        self.running = False

    def SvcDoRun(self):
        servicemanager.LogInfoMsg("MyPythonService is starting.")
        self.main()

    def main(self):
        while self.running:
            # Your service logic goes here
            time.sleep(5)
            servicemanager.LogInfoMsg("MyPythonService heartbeat.")


if __name__ == '__main__':
    win32serviceutil.HandleCommandLine(MyService)

Python 3.13.0 : how to install pywin32_postinstall.

Today a tutorial on how to install pywin32_postinstall.

This package is essential for accessing Windows-specific functionalities in Python.

The pywin32_postinstall missing python error typically occurs when the pywin32 package is not properly installed or the post-installation script is not executed correctly.

Fisrt install the pywin32 python package.

pip install pywin32

The next step is to run this command on the path with Script folder.

python C:\Python313\Scripts\pywin32_postinstall.py -install
Parsed arguments are: Namespace(install=True, remove=False, wait=None, silent=False, quiet=False, destination= ...

The next step is to run this command on the path with Script folder.
