How to Configure Symbols for Killswitch?

Like in Process Explorer, or Process Hacker I insert
SRVC:\Users[i]Administrator[/i]\AppData\Local\Temp\symbolsSymbol information
but nothing happens, no symbols are loaded
What is wrong?

EDIT
Isn’t it that dbghelp.dll that is in the installation folder doesn’t allow symbols to be downloaded and has to be changed with the one available, for example, with “Debugging Tools for Windows”?
