Looks like you are trying to open a 64 dll on a 32bit windows system. This will not work.

I have 64bit Windows system. What should I do then?

Hi @LOSTSVUND

From Googling, it appears that this is caused by a conflict (difference) between the version of python that Blender and the addons use, and the other version of python that you have on your computer.

From your screenshot, I can see that Blender is loading your version of numpy instead of the one included with Blender.

You could uninstall your version of python and see if that fixes your issue.

try staring blender with the blender_factory_startup.cmd batch file located in the blender folder, does it load properly using that?

Hi, I've uninstalled Python via Apps & Features from Control Panel. Still doesn't work

I looked into Blender folder and found blender_factory_startup.cmd there. And Blender works fine with that. Should I remove it or..?

Just to double check, when you start blender with the blender_factory_startup,cmd batch file you can enable the addon you want and everything works?

Well, I deleted all Python references that could possibly cause incorrect work of Blender. And also Re-installed Blender. And now the add-ons are activating

@LazyDodo pointed me to this report.
Suspect this is either:

An incompatible numpy DLL which is getting found instead of the one Blender provides.
An issue in with the encoding of the path name, causing _dlopen to fail (this seems unlikely, mentioning it as a possability).

This needs someone who can redo the error to output the path _dlopen is attempting to load, to see why this keeps happening.

In ctypes/__init__.py make the following edit, adding lines above the _dlopen call:

P1201: Snippet to debug #72796

        # Add these lines.
        if handle is None:
            print("Check for error loading path:", self._name)
            _sys.stdout.flush()
        # End added lines.


        if handle is None:
            self._handle = _dlopen(self._name, mode)
        else:
            self._handle = handle
