Python installer: "0x80070642 - User cancelled installation"

3

Whenever I try to install Python 3.6.3 (32-bit) to my Windows 7 laptop at work, the installer fails with the following error.

0x80070642 - User cancelled installation

This error consistently occurs half-way through the installation while installing "Python 3.6.3 Standard Library (32-bit)", as indicated by Python's progress bar turning red in the taskbar icon.

Looking at the installer log, I noticed a few entries which report Failed to secure cache path:, but searching these errors hasn't provided any additional details.

Error 0x80070005: Failed to secure cache path: C:\ProgramData\Package Cache\
Error 0x80070005: Failed to secure cache directory: C:\ProgramData\Package Cache\

I was able to resolve the error by unchecking 'Install launcher for all users'

Once unchecked, the installer worked as expected without any issue.

Installer with "install launcher for all users" unchecked
