How to silently install & uninstall the CodeTwo Signatures Add-in for Outlook

Problem:

You want to perform a silent installation of the CodeTwo Signatures Add-in for Outlook for your users without using Group Policy Objects (GPO) or Microsoft Intune.

Info

This article is about CodeTwo’s classic (COM) Outlook add-in that works with Outlook for Windows. If you want to have CodeTwo email signatures in Outlook and also in Outlook on the web (OWA), use our modern CodeTwo Signatures Web Add-in (co-engineered with Microsoft) instead. The Web Add-in offers simpler deployment via the Microsoft 365 admin center and does not require users to log in to the add-in in their Outlook – it’s enabled on their Outlook accounts automatically. See deployment guidelines

Solution:

If you want to install the CodeTwo Signatures Add-in for Outlook for a group of users or all users in your organization at once, it is recommended to deploy the add-in via GPO or Microsoft Intune. If, for some reason, you cannot use these methods, you can use the msiexec command instead.

Important

Things to keep in mind while using msiexec:

  • If you install the CodeTwo Signatures Add-in for Outlook while Outlook is running, the add-in will be launched as soon as the user restarts Outlook.
  • If you uninstall the CodeTwo Signatures Add-in for Outlook while Outlook is running, the uninstall process will take place immediately and Outlook will restart automatically.
  • Installing the add-in by using the MSI file (no matter if you deploy it via GPO or msiexec) means that your users will not have the add-in updated automatically. If possible, it is recommended to use the manual deployment method.
  • You need to launch the Command Prompt / PowerShell as current user (local admin rights are not required to install the add-in). Running the msiexec command from another user profile (for example, by using run as administrator option to start the PowerShell console) doesn’t let you install the add-in correctly.

  1. Open the Command Prompt (cmd) or Windows PowerShell console as current user (not as administrator) and run the following command:
msiexec /i <MSI installer> /qn

where <MSI installer> is the location where you downloaded the MSI installer for the add-in, for example:

\\MyServer\netlogon\CodeTwoSignaturesAddinForOutlook.1.1.60.msi

  1. The add-in should install in a few seconds. Once it is installed, it will be ready to use the next time the user starts their Outlook.

Uninstalling the CodeTwo Signatures Add-in for Outlook with msiexec.exe

To silently uninstall the add-in, you can use the following command

msiexec /x <MSI installer> /qn

where <MSI installer> points to the MSI file that you used to install the add-in in the first place. If the MSI file is no longer accessible, you can use the add-in’s ID number. For example, in the case of version 1.1.60 of the add-in, the command would be:

msiexec /x {3FD19196-FC60-4CD9-A0E9-322846E562BB} /qn

To check the ID number of the currently installed version of the add-in, use the following PowerShell cmdlet:

Get-WmiObject -Class Win32_Product | where name -eq "CodeTwo Signatures Add-in for Outlook"| select Name, Version, identifyingnumber
