Cannot load VSTO deployment file for Outlook Addin

I am trying to install an Outlook plugin that was developed using C# on .Net Framework and was published using click once manifest. However i am getting below error whenever i try to install the vsto file . enter image description here

Solution

  • Try renaming VSTOInstaller.exe.config file to VSTOInstaller.exe.config.bak because I believe VSTO Installed does not require the config file.
