Python is not installing and keeps throwing an error

Whenever I try to install Python it says Python not installed.

The error code is 0x80070643.

I have uninstalled Python and the launcher.

It looks like this is a known issue and you will need to repair the installation file before uninstalling it.

Here's a link to a bug article: https://bugs.python.org/issue32966.
