According to various web pages, orca.msi/orca.exe is primarily distributed as part of the Windows SDK.
I have Visual Studio 2015 Professional Update 3 installed. I have installed all the "Universal Windows App Development Tools" components, which includes three different versions of the Windows 10 SDK (10.0.14393, 10.0.10586, 10.0.10240).
But I can't find orca.msi or orca.exe anywhere on my machine. Is this tool no longer packaged with the Windows SDKs? Do I need to install one of the older Windows SDKs as well? Is there an optional Visual Studio 2015 component that I can install to get Orca?
An MSDN page for orca.exe eventually leads me to a download page for Microsoft Windows SDK for Windows 7 and .NET Framework 3.5 SP1. Is this the most recent SDK which includes orca.msi, or can it be found in newer SDKs such as the Win7/.NET4.0 or Windows 8 or Windows 8.1 SDKs?
You can pick it from Windows SDK ISO.
Installers. You can find the Orca-x86_en-us.msi.
