Hoxhunt button: Special - Installing stand-alone Hoxhunt Outlook COM add-in


Hoxhunt add-in is also available as a stand-alone COM add-in. This version can be used in highly secured and restricted environments where the use of Exchange Web Services API is completely forbidden. 

COM or VSTO add-ins are earlier Office integration solutions that run only in Office on Windows.

DISCLAIMER: Please discuss this option with your Hoxhunt Onboarding Manager before installing the COM add-in. Hoxhunt is not actively developing this add-in type. It is lacking many features and is more simplistic in its design. Before installing this version, we highly recommend to consider our Officejs add-in which is based on Microsoft's modern Office add-in architecture.


There are two installation package options available. Please select the one suitable to your environment.


Install using InstallShield Installer (Setup.exe)

Ask for the installer package from Hoxhunt Support.

The Setup.exe package can be installed silently with the following switches:
/s /v"/qn"


Installing using SCCM (HoxHuntPluginInstaller.msi)

Ask for the installer package from Hoxhunt Support.


NOTE: HoxHuntPluginInstaller.msi doesn't include dependencies.
When installing .msi via SCCM make sure you add the following dependencies when installing:

  • .NET 4.5.2
  • VSTO 2010 (Visual Studio 2010 Tools for Office Runtime)

Notes for installing VSTO 2010

Microsoft hasn't officially provided an .MSI version of Visual Studio 2010 Tools for Office runtime (vstor_redist.exe).

Sometimes .EXE files might refuse to run and install successfully via SCCM. SCCM works better with .MSI installers. However, you can try to extract the .MSI from the .EXE in a couple of ways:

  1. Download the vstor_redist.exe from https://www.microsoft.com/en-us/download/details.aspx?id=48217
  2. Extract the vstor_redist.exe with 7-Zip and look for .MSI folder or files.
  3. Start vstor_redist.exe, don't proceed with the wizard, and look inside your %temp% folder for the MSI.
  4. Extract contents of vstor_redist.exe via command line and look for the MSI:
    <file.exe> /s /x /b"<target-folder>" /v"/qn"

NOTE: if VSTO is already installed on the machine you run this command, it will uninstall itself.
