How to include a Microsoft Visual C++ Redistributable package in a python cx_freeze application

CONTEXT

I'm trying to build a python tkinter application using cx_freeze, and I successfully build the .exe. Here is my setup.py:

import sys
from cx_Freeze import setup, Executable

version = "0.7.6"
author = "Me"

base = None

if sys.platform == "win32":
    base = "Win32GUI"

build_exe_options = {"include_files": ["assets/", "files/"], "excludes": ["matplotlib.tests", "numpy.random._examples"], 
"include_msvcr": True}

setup(
    name="Application",
    version=version,
    description=f"Application {version}",
    author=author,
    options={"build_exe": build_exe_options},
    executables=[Executable(script="main.py", base=base, targetName="App.exe", icon="assets/Logo.ico")]
)

IDENTIFICATION OF THE PROBLEM

However, some libraries I use in the Python code, like matplotlib, can only be compiled with Visual Studio 2015 or later (see the documentation). I have Visual Studio 2019 on my computer so everything works fine on it but I tried running the app on another Windows computer which only has Microsoft Visual C++ 2010 Redistributable package (and I guess the 2010 compiling tools), and the app crashed before lauching with this main error:

ImportError: DLL load failed while importing ft2font: the specified module was not found.

Based on the discussions here, I figured this error means that Visual Studio requirements are not met (i.e 2015 or later) and as indicated at the end of this discussion, matplotlib wheels don't include C++ runtime DLLs for version > 3.3.0. Before asking my question, I must say my understanding of how python libraries are compiled or what wheels are is very limited and I don't even really know which C++ runtime DLLs are involved in the compilation of my built application.

QUESTION

How can I include Microsoft Visual C++ 2015 Redistributable package (assuming that is legal) in my app?

A simple solution for me would be to include all necessary dependancies in my project without having the user to install a Visual Studio C++ 2015+ version on its computer, so if you have any idea on how to achieve that with cx_freeze or even some other tools I might look into, I thank you in advance for your help.

P.S: as you can see, I tried the "include_msvcr" key from the build_exe_options but that didn't solve my problem (plus I think msvcp.dll is included by default)

UPDATE

I manually included vcruntime140_1.dll, msvcp140_1.dll in the directory and the app is now launching, but the window is not displayed correctly, its frame doesn't appear, so problem not solved yet.

If Windows Kits is installed, you should go to the C:\Program Files (x86)\Windows Kits location and decide on your appropriate python architecture. If the application is 64bit, a location type is created: C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x64

You must copy all the DLLs.

However, this may not work well. I recommend running the dependency tool. This helps you find the right DLLs.

Dependencies

You should analyze the pythonVxVx.dll (python38.dll) file and the yourapp.exe file.
