I´m using Microsoft Visual Studio 2005. I use the ClickOnce feature to publish an update to this application. I receive the following error messages:

Error message 1
Cannot publish because a project failed to build.

Error 2 SignTool informó de un error 'Error al firmar bin\Debug\Biblioteca.publish\\setup.exe. SignTool Error: ISignedCode:ign returned error: 0x80880253

The signer's certificate is not valid for signing.

SignTool Error: An error occurred while attempting to sign: bin\Debug\Biblioteca.publish\\setup.exe

'. Biblioteca


I dont´t know how resolve this problem . I download the NDP20-KB919472-X86.exe package from Microsoft but I can´t install it, Windows Installer give me a error too.

Can anybody herlp me ?

What are you signing your deployment with? A certificate that you purchased, or are you trying to not sign it?

Under the Signing tab for your main project, check "Sign the ClickOnce manifests".

Click on "Create Test Certificate" to create a test certificate and use that one.

If you have a certificate that you purchased from Verisign or someone like that, you should select *that* certificate instead of a test certificate.
