Outlook Add In ClickOnce error RRS feed

  • Question

  • Sorry if this is the wrong area, but now I am receiving another error when trying to install my Outlook add in using ClickOnce on another computer, despite it being signed with a certificate.

    "Customized functionality in this application will not work because the certificate used to sign the deployment manifest for **** or it's location is not trusted.

  • Hello Darryl,

    The Troubleshooting Office Solution Security page states the following:

    Internet Explorer Enhanced Security Configuration (IEESC) in Windows Server 2003 and higher, and Internet Explorer 7 and higher, significantly restricts the ability of users to browse the Internet. When users try to install Office solutions from a network file share or web location, they might get the following error message: "Customized functionality in this application will not work because the certificate used to sign the deployment manifest for SolutionName is not trusted. Contact your administrator for further assistance."

    With IEESC and Internet Explorer 7 and higher, if the URL of the deployment manifest is categorized in the Internet zone, the manifest must have a certificate from a trusted publisher or the solution cannot be installed. Without IEESC, the default behavior is to prompt the end user to make a trust decision.

    To manage the effect of IEESC and Internet Explorer 7 and higher, identify web sites and universal naming convention (UNC) paths that you trust and add them to one of the trusted security zones (Local intranet or Trusted sites).For information about how to manage zones, see Configuring ClickOnce Trusted Publishers.

  • It's weird there is no prompt at all, it just flat out denies it?

    And it runs on some operating systems. It wouldn't run on Win 8.1 Enterprise Edition.

  • Did you try to add the path to the installer to the trusted security zones?
