Code-signing

We are having some issues with our C Sharp .NET 4 Application

We are using Visual Studio 2010 to build a Click Once Installation

In addition, we use our code-signing certificate (.pfx) to sign the package

However when attempting to install the application it is blocked by

Windows 8 Smart Screen with an “unknown Publisher” message.

We sign our package twice once on the actual files and afterward

The manifest is resigned.

Hi Rene,

>>“unknown Publisher” .

Please check whether you sign file in the correct directory.

Reference:

A document shared us the detailed steps for "Certificate Expiration in ClickOnce Deployment".

In addition, since this issue is related to the Clickonce, I suggest you post a new case in this forum:

http://social.msdn.microsoft.com/Forums/windows/en-US/home?forum=winformssetup , and there you would get dedicated support.
