Visual Studio Emulator for Android fails to install - says Visual Studio is required

I am trying to install the standalone Visual Studio Emulator for Android on Windows 10 Pro. According to the page, Visual Studio 2015 is not required and I've had the emulator installed on running on this machine previously under Windows 8.1.

Before the emulator, I installed Visual Studio 2013 Professional, SQL Server 2016 Developer Edition and the June 2016 SSMS package, and SQL Server Developer Tools, as well as Android Studio. Some of the SQL Server tools installed the Visual Studio 2015 Isolated and Integrated shells, so I don't know if that's confusing the installer into trying to install the Visual Studio extension into a non-supported version. Uninstalling/removing the SQL tools is not a simple process as it completely litters the program list with dozens of items.

The installer says "Microsoft Visual Studio Emulator for Android (Visual Studio Extension) Fatal error during installation." and the log file contains these lines:

Since it should be possible to use the emulator without Visual Studio, I don't know why it aborts the entire installation when it can't install the extension, or how to get it to continue without it.

I don't want to have to install the entire Visual Studio 2015 product because I don't qualify for the Commmunity edition and I'm already using Visual Studio 2013.
