What is the correct way to use Advanced Installer to digitally sign an Office 2007 Add-In. When installing the plugin we get the message 'Publisher cannot be verified'.
We have written an Office 2007 Add-In using Visual Studio 2010/.NET 3.5 SP1/VB.NET. The output that VS2010 creates (.vsto, .manifest, .dll) etc where included into the AI project as per the wizard. In the AI project we have setup the Digital Signature. We know the certificate is good as we regularly use that .pfx file to sign various exe's, dll's etc without any issues.
