Error Code 0x80070643

I found it.

if you are not administrator of the system, and change the location of installation, for example (c:\python) this error will be appear. so you must be install python on (c:\users\'your username'\App Data\Local\Programs\Python)

and after installation python go to system environment and add the path into this.

Answer 5

I accidentally copied the python folder from the installed location into my C drive and encountered this problem. Following steps worked for me.

1. Run the Python installer (.exe) file
2. Select the repair option, let it process.
3. Run the Installer again. This time select uninstall and let it process
4. Run the Installer again and this time go with the customization option and check the Add path option also.

open cmd and type python --version, if it displayed python version. You are good to go.

Windows 10. Had this issue from a while and after a lot of hit & trials, finally resolved it. Downloaded the Windows troubleshooter. Removed every application option with Python's name as suffix, and tried uninstalling from Control panel. It worked. And then I installed the required python version with ease.
