0x80070643 python как исправить

I had the same problem installing Python version 3.9 for the first time on my Windows 10, as this same problem happens to many users trying to install Python, the best solution I accidentally, just like @MANAN AGGARWAL discovered trying to check if I already had a version of Python installed on my computer by the DOS Command Prompt, was:

Open the DOS Command Prompt (cmd) and dictate “python”: if a screen shows you a version, it’s clearly not the first time you’ve installed Python, so if you want to upgrade you should try: https: / /www.delftstack.com/en/howto/python/how-to-update-python/ But if you’ve never installed any version of Python, the solution lies in updating your operating system to the latest version through Windows Update, and open the command prompt and type Python, or go directly to the Microsoft Store and search for Python followed by its latest version. It works without error.
** If by chance it does not automatically install on your PC after downloading, click “install on my devices” and select your computer name.

Why can’t I install Python directly from the website file? Please note that when trying to install any software/applications from outside Microsoft’s trusted locations, there are high chances of user settings interfering with the installation. When coming, for example, from the Microsoft Store, a chance of success is much greater, even without having problems related to User Permission Settings.

Another important thing to point out here is that installing a lot of software from outside Microsoft’s trusted platforms can cause you to change some user permissions which can have positive effects with some software and negative effects with others, even with security your own system if you don’t know what you’re doing.

We python when using this software, sometimes on the same computer may need to install a different version of python software. For example, I installed the python 3.6.5 version, and now want to use python.3.6.1 version, then I have to uninstall python3.6.5 version, otherwise it is the same version of the software python3.6 can not reload. I used to use third-party software to uninstall unwanted software, the result turned out, it can not be uninstalled. Meanwhile Fatal error during installation error 0x80070643 python
