What version of Python did you install?

[jorge-datanalyst]

Python = 3.8.10
ISO Widows 10 on VMware

• Copy files "pythoncom38.dll" and "pywintypes38.dll" from folder "pywin32_win32" (Lib/site-packages) to system directory "win32".
• Make sure path folders "dll", "site-packages" and "scripts" are set within system environmental variable "Path".
• Add system variable "PYTHONPATH" with same paths of the previous folders.

Thanks for your reply, don't need to do that.

The following worked, I reassembled the development environment from scratch and then I did the steps in your guide, but unlike the previous test I skipped the step C:\OpenOPC37\bin> net start zzzOpenOPCService from the section "Start the OpenOPC Gateway Service "and go directly to the next step which is to run the command C:\OpenOPC37\src> python OpenOPCService.py debug in the terminal.

I don't know if what I did makes any sense or it was just my mistake in the beginning but this worked for me.

Another change I made was to assign the value 127.0.0.1 to the variable OPC_GATE_HOST since for now I am doing tests on my premises.

Thank you again for your help.
