Microsoft vsto addin for outlook installation showing unknown publisher on installation RRS feed

  • Question

  • Hi there,

    I have made a very simple vista-add-on for outlook 2013.The plugin works fine but when I package it using the advanced installer program and run the setup after installation this popup appears.

    Do I need a code signing certificate to make it a known publisher. If so, then what type of certificate files I need and where I can get the cheapest one?

    Thanks.
