SignTool Error: Invalid option: /fd

I publish my exe and activate auto updates.

But when I compile the exe, there is an error:

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

So I couldn't publish.

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.

I have to add a certificate from "Sign the ClickOnce manifest" but now it gives the "SignTool Error: Invalid option: /fd" error.

How can I solve this problem?

I encountered the same error message when migrating an old ClickOnce project from VS2008 to VS2017. It seems my VS2008 was using an old version of SignTool.

I found (and succeeded with) a tip to change registry key HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Microsoft SDKs\Windows to make Windows to use newer SDK (in my situation SDK v8.1A was the most recent).

The original tip can be found here: https://social.msdn.microsoft.com/Forums/en-US/a39b9f82-aaec-4bbd-8cb2-3cade50796ba/an-error-occurred-while-signing-failed-to-sign-bindebugapppublishprogramexe-signtool-error (scroll down to answer by nikidimi)

Go to the myapp.csproj file, which is the project file, and search for 'SignManifests' PropertyGroup, change the value to false, and the error disappears. This worked for me.

I did just the opposite as Stefano - changed it from sha256RSA to sha1RSA - and then it allowed me to publish without the error.

Just changing the signature algorithm may do the trick.

I had to change the Signature Algorithm to sha1RSA from sha256RSA
