# 📋 Outlook Add-In (classic): Downloads & System Requirements

This article provides the current installation files (MSI) for the Outlook Add-In and explains the mandatory requirements for software deployment.

## **Current Version & Status**

> **Please always use the latest version of the FTAPI Outlook Add-In.**
> 
> Current version: **4.9.1**
> 
> *FTAPI administrators receive a notification once a week about users who are using an outdated version.*

## **Download: Outlook Add-In**

Here you will find the current MSI package. Please note the information below regarding the distinction between the installer packages.

**Compatibility note:**  
The version of the FTAPI Outlook Add-In always depends on your Windows operating system, not on the installed Office version. Since 32-bit systems no longer reflect the current state of the art, we offer our add-in exclusively as a 64-bit version to ensure maximum performance and security.

### **Which installer is the right one?**

The downloaded package contains two different .msi files. Please select the file that matches your use case:

-   **Small\_Installer (mandatory for software deployment):**   
    Contains only the FTAPI Outlook Add-In. This installer must be used for automated deployment, as it does not install any dependencies.
-   **Full\_Installer (for manual installation only):**   
    Also contains the necessary Windows components (.NET, VSTO, WebView2). Since MSI packages technically cannot trigger further MSI installations in the background, this installer is not suitable for software deployment.

> **Note: Outlook must be closed during installation.**

## **Requirements for software deployment**

Since only the **Small\_Installer** can be used for software deployment, missing dependencies are not automatically installed.

Therefore, make sure that the following components are **deployed/installed in advance** on the target systems. If these are missing, the add-in will not load.

| **.NET Framework** | **VSTO 2010** | **WebView 2 Runtime** |
| --- | --- | --- |
| **\>** [**At least .NET Framework 4.8**](https://dotnet.microsoft.com/en-us/download/dotnet-framework/net48) | [**\> VSTO 2010 Runtime**](https://www.microsoft.com/en-us/download/details.aspx?id=105671) | **\>** [**WebView 2 Runtime**](https://developer.microsoft.com/de-de/microsoft-edge/webview2/?form=MA13LH#download) |
