Installation Steps

Installation steps will vary depending on your organisation’s Microsoft Office setup and deployment approach.

For most Microsoft 365 organisations, centralised deployment via the Admin Centre is recommended, as it allows the add-in to be rolled out and managed across users.

A manifest file is typically required for local installations or where the add-in is deployed as a custom app. Avvoka can provide this file on request.

Please refer to the relevant section below:

  • Microsoft 365 organisations – see App Store Installation or Centralised Deployment (Microsoft 365)

  • Windows environments (local setup) – see Local Installation (Windows)

  • macOS environments (local setup) – see Local Installation (macOS)

App Store Installation

The add-in can be installed directly from the Office Add-ins store.

Steps:

  • Open Microsoft Word

  • Go to Add-ins → More Add-ins (from the Home or Insert tab)

  • Search for Avvoka

  • Click Add to install

This installation method can also be used for organisation-wide deployment. For more information, see Centralised Deployment (Microsoft 365).

Centralised Deployment (Office 365)

The Avvoka add-in can be deployed across your organisation through the Microsoft 365 Admin Centre.

Step 1: Access the Admin Centre

Step 2: Choose a deployment method

Option A — Install from the Microsoft catalogue

  • Select Get Apps

Option B — Deploy as a custom app

  • Upload the manifest file provided by Avvoka

  • Assign the add-in to the relevant users or groups

  • Approve any required permissions

  • Complete the deployment

Step 3: Access the add-in

  • Once deployment is complete, users can access the add-in in Microsoft Word

  • Users may need to restart Word

  • In some cases, it may take a short period of time for the add-in to become available

Local Installation (Windows)

This installation method uses a manifest file provided by Avvoka to make the add-in available locally.

Step 1: Set up a shared location

  1. Create a folder to store the add-in manifest file (this can be in any location).

  2. Right-click the folder and select Properties.

  3. Open the Sharing tab.

  4. Select Advanced Sharing and enable Share this folder.

  5. Place the manifest.xml file in this folder.

  6. Copy the Network Path shown in the Sharing tab (for example: \\USERNAME\Documents\AddIns).

Step 2: Register the location in Word

Each user must complete this step once in their Word desktop application:

  1. Open WordFileOptions.

  2. Select Trust Centre from the left-hand menu

Local Installation (macOS)

The add-in can also be installed locally on macOS using a manifest file provided by Avvoka.

Step 1: Close Microsoft Word

Ensure Microsoft Word is fully closed before proceeding.

Step 2: Add the manifest file to the local add-ins directory

  • Open Finder

  • From the menu bar, select Go → Go to Folder

  • Enter the following path and click Go:
    ~/Library/Containers/com.microsoft.Word/Data/Documents

  • Within the Documents folder, create a folder named wef (if it does not already exist)

  • Drag the provided manifest.xml file into the wef folder

Step 3: Open the add-in in Word

  • Reopen Microsoft Word

  • The Avvoka add-in should now be available

  • You can access it via the Add-ins option or directly from the toolbar (depending on your Word configuration)

Technical Overview

The Avvoka Work-in-Word add-in is a JavaScript-based Microsoft Word Add-in built using the Microsoft Office Add-ins platform.

The add-in runs inside Word’s embedded web browser and connects securely to the user’s Avvoka environment.

Key components of the architecture include:

  • Manifest file – An XML file used to install the add-in and configure how Word loads the application.

  • Embedded browser – Word hosts the add-in inside a built-in browser (typically Chromium-based WebView2).

  • Server connection – The manifest directs Word to the organisation’s Avvoka server URL.

  • Authentication – Users authenticate via Avvoka’s standard authentication model, including support for Single Sign-On (SSO) where enabled.

User permissions within the Word add-in mirror the permissions configured in the Avvoka web application.

Troubleshooting

Centralised Deployment (Microsoft 365)

Issue: Unable to upload manifest file

  • Confirm you have the required administrator permissions (e.g. Global Admin)

  • Ensure your Microsoft 365 environment supports centralised add-in deployment

Issue: Add-in not visible in Word

  • Fully close and restart Microsoft Word

  • Allow time for the deployment to propagate (this can take several hours, and in some cases up to 24 hours)

Issue: Add-in still not visible after 24 hours

  • Verify the add-in has been assigned to the correct users or groups

  • Ensure the user is signed into Word with the correct Microsoft account

Local Installation (Windows)

Issue: Unable to configure shared folder (Advanced Sharing)

  • Administrator permissions may be required to enable folder sharing

Issue: “Add-ins” option not visible in the ribbon

  • Go to File → Options → Customise Ribbon

  • Locate the Add-ins option (typically under the Insert tab) and enable it

Issue: Add-ins button is disabled

  • This may be restricted by permissions or IT policy

Issue: Unable to add a trusted location

  • Ensure that Allow Trusted Locations on my Network is enabled

Issue: Trusted locations setting is disabled (greyed out)

  • This is likely controlled by your organisation’s IT policy and may require administrator access

Post Installation

Issue: Error message when opening the add-in

  • Check whether any organisational policies restrict third-party add-ins

  • Confirm that Word can access the internet (e.g. no VPN, proxy, or firewall blocking requests)

Issue: Add-in loads but appears blank

  • Verify that your version of Word is supported
