If it does not code-sign your setup.exe and the uninstall.exe then you are using an incorrect SHA-2 (or "dual" SHA-1/SHA-2) code-sign configuration in your project. Check your password, your SHA-2 based code-signing certificate. And make sure that you are using the correct signtool.exe.

Does this help?

BTW, you can post the compiler output here and I can tell you exactly what you are doing wrong.
