Getting msbuild.exe without installing Visual Studio

How do you get msbuild.exe without installing those crazy Visual Studio programs?

I need it for an npm install to finish working. I'm on Windows 7 and can't get on older version of Visual Studio 2013 Express online.

The latest (as of Jan 2019) stand-alone MSBuild installers can be found here: https://www.visualstudio.com/downloads/

Scroll down to "Tools for Visual Studio 2019" and choose "Build Tools for Visual Studio 2019" (despite the name, it's for users who don't want the full IDE)

See this question for additional information.

It used to be installed with the .NET framework. MsBuild v12.0 (2013) is now bundled as a stand-alone utility and has it's own installer.

To reference the location of MsBuild.exe from within an MsBuild script, use the default $(MsBuildToolsPath) property.

You can also get the MSBuild executable as a Nuget package https://www.nuget.org/packages/Microsoft.Build.Runtime/.
