Answer 1

SignTool is moved to another location in the last SDK: C:\Program Files (x86)\Windows Kits\8.1\bin\x86

Need to install ClickOnce Publishing Tools during Visual Studio 2015 setup.

You can re-run the Installation from the Programs and Features section; find Visual Studio in the list and click Change.
