[Python] Python installer won't install pip on Windows 8.1, error on unknow DLL

I'm trying to install Python on a computer with Windows 8.1 x64, and every time I tried, the installer won't install pip.
I started with Python 3.13, then 3.11, 3.10 (all of them x64), and the last time I tried 3.9. This is the message when I run

python -m pip

%USERPROFILE%\AppData\Local\Programs\Python\Python39\python.exe: No module named pip


This is the message when I tried python get-pip.py:

I even tried python pip.pyz install pip, got the same error (I know I could have used just pip.pyz install pip):

This is the error that I got using python -m ensurepip:

Now, this are the files installed in

LICENSE.txt
NEWS.txt
python.exe
python3.dll
python39.dll
pythonw.exe
vcruntime140.dll

And these are the files that contain pip under

C:\Users\USER\AppData\Local\Programs\Python\Python39

Lib\test\test_pipes.py
Lib\ensurepip\_bundled\pip-22.0.4-py3-none-any.whl

And this is the first message that I get when I run python:

Python 3.9.13 (tags/v3.9.13:6de2ca5, May 17 2022, 16:36:42) [MSC v.1929 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

I've been through the messages that mention something similar, but the problems are just not the same, and neither is solved updating the c++ libraries (they're updated), or using get-pip.py or pip.pyz.
The bigger problem, is that I can't create virtual environments, because the program tries to install pip, which lead us to this point.
What am I missing?
And please, for the @admins, I know there are similar questions, but non with a problem like this, or with a solution that works for me for that matter. Thanks!
