[New-bugs-announce] [issue31694] Running Windows installer with LauncherOnly=1 should not register the version as installed

[Tzu-ping Chung]

New submission from Tzu-ping Chung <uranusjr at gmail.com>:

After running

    python-3.6.2-amd64.exe /quiet LauncherOnly=1

Python 3.6.2 is registered as installed, even though nothing is actually installed.

Running the installer again at this point shows an error indicating “this product is already installed”, and does not show me the usual repair/modify/uninstall options.

I have to run uninstallation with Control Panel before the installer works again.
