Visual Studio SignTool.exe Not Found

I had the same issue but installing the Windows 8.1 SDK as per Catquatwa’s answer did not work for me (signtool.exe was still missing from C:\Program Files (x86)\Microsoft SDKs\Windows\vX\Bin).

I stumbled across this solution: http://www.benedykt.net/2015/08/12/missing-signtool-exe-w-visual-studio-2015/

Basically, for VS 2015, this would be:

  • Open Programs and Features
  • Select “Microsoft Visual Studio 2015” and click “Change”
  • Press “Modify” to progress to Features options
  • Select “Windows and Web Development”, then tick “ClickOnce Publishing Tools” for installation
  • Then “Next” and then “Update”
