BUILD FAILED

Avik’s suggestion is incorrect. Visual studio does not need to be reinstalled. Please navigate to your Control Panel > Programs & Features > Microsoft Visual Studio 2015 and select “Change” and then “Modify” in the window that appears. It will list multiple modules that can be installed with Visual Studio 2015. Please select “Common Tools for Visual C++ 2015” and then install them. This should fix the problem.

Reinstalling would not resolve this unless you happened to select that module when reinstalling.

Reinstall Visual Studio, it should fix this.
