title: 0x80070643 error while installing Python 3.6
body: <p>I'm actually using Python for an audio steganography project but I have some troubles.
  I searched this error code on the forum, but I found things about SQL installations and not Python.</p>
  
  <p>I'm trying to re-install Python 3.6.5 after an uninstall, because of a bug with pip.</p>
  
  <p>I installed Python 2.7, Python 3.6.5, Python with VS 2017, before uninstall it because it wasn't working.</p>
  
  <p>However, when I'm runing the installer as an administrator, hit "customize installation", tick everything excpet "balblalblabal (this requires VS 2015 or later)", and click on "install", it tells me that :
