I performed a custom install for all users on my E: drive (E:/installs/python3). Added it to the path. It is not under my specific user account. My understanding is this is a global install.

What exactly is E:? If anything other than a local device it might not be available to the user running the service.

I then run it under administrator privileged cmd and successfully install the service.

Looking at security permissions for pythonservice.exe in the root python directory. SYSTEM and Admin users have full control.

To be clear, the entire Python tree will need those permissions, not just that .exe. And the question is whether the user running the service has access - SYSTEM and Admin should cover many common scenarios, but not all. You could try configuring the service for your specific user just to see if it works - if it does it would still point to user permissions.

The "<Error getting traceback - traceback.print_exception() failed>" part sounds like it is failing to find Python itself. Where is Python installed? Is it possible the user running the service can't access that location? I believe Python being installed in the default location could cause this if the server is running as any other other than the user which installed Python.

Currently experiencing this issue on my Windows machine when installing a Windows Service. This is the error output I get from running in the cmd as administrator. Restricting me from being able to run my services.

Here is the output from event viewer application log:

|The description for Event ID 14 from source Python Service cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event.

This issue has happened on each of these version I've tested Python3.11, 3.10.10 and 3.10.8.

Currently running Python 3.10.8 64 Bit on Windows Server 2016.

- I've installed pywin32

- Run post_install in the root directory of python310

- Installed the service with install flag

- Attempted to start service with start flag

- PythonService was unable to locate the service manager. Please see the event log for details.
