title: SignTool Error: Invalid option: /fd
body: <p>I publish my exe and activate auto updates.</p>
  
  <p>But when I compile the exe, there is an error:</p>
  
  <blockquote>
    <p>Severity  Code    Description Project File    Line    Suppression State Error An
    error occurred while signing: Failed to sign
    bin\Debug\app.publish\myapp.exe. SignTool Error: Invalid option: /fd</p>
  </blockquote>
  
  <p>So I couldn't publish.</p>
  
  <p>When I try to uncheck "Sign the ClickOnce manifest" the error is gone
  but I couldn't install the package because Windows doesn't allow and the Windows Defender SmartScreen blocks my app because there's no certificate.</p>
  
  <p>I have to add a certificate from "Sign the ClickOnce manifest" but now it gives the "SignTool Error: Invalid option: /fd" error.</p>
  
  <p>How can I solve this problem?</p>
