[issue26413] python 3.5.1 uses wrong registry in system-wide installation

[Mike]

New submission from Mike:

The installer for python 3.5.1 (observed with the x64-86 executable installer, 
assumed to happen with all installers) allows users to install python either 
just for themselves or do a system-wide installation (provided they have 
sufficient privileges).

However, when selecting a system-wide installation, the uninstall information 
is registered to a key under HKEY_CURRENT_USER.

The result of this is that any user can run python 3.5.1; however, the entry in 
the "uninstall programs" list shows only for the original user that installed 
it.

This is in contrast to previous versions of python (e.g. 3.4.4) where any user 
could uninstall it (provided they have sufficient privileges). It is also in 
contrast to pylauncher of the same version (i.e. 3.5.1) which properly 
registers itself under HKEY_LOCAL_MACHINE when selected to be installed for all 
users.

The key in question is at this path:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Uninstall\{b8440650-9dbe-4b7d-8167-6e0e3dcdf5d0}

I believe it should be here:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\{b8440650-9dbe-4b7d-8167-6e0e3dcdf5d0}
