Deploying the VT Writer add-in will require supplying the add-in manifest file. The manifest file can be retrieved from the VT Writer application at 


Deploying Add-In

An app catalog is a dedicated site collection in a SharePoint web application or SharePoint Online tenancy that hosts document libraries for Office and SharePoint Add-ins. To make Office Add-ins accessible to users within their organization, administrators can upload Office Add-in manifest files to the app catalog for their organization. When an administrator registers an app catalog as a trusted catalog, users can insert the add-in from the insertion UI in an Office client application.

Instruction for Users

Once the I.T Admin has completed the above step the users can install the Add-In by opening their Word application > Insert Tab> My Add-ins > A pop-up will appear with VT Writer Add-In.



Deploying the add-in using a local Windows Network Share

Create a network share that your VT Writer users have Read access to (Note: The file needs to be available when a user loads Word and the add-in starts. If the file is installed behind a firewall, the add-in may be unavailable if a user is not on your corporate network or VPN.). Download the manifest.xml file from the VT Writer server ( and place it in the new share. Once this is complete, end-users will be able to add this as a Trusted Add-In Catalog.


Open up the Word Add-In Catalog options via File->Options->Trust Center -> Trusted Add-In Catalogs, then select Add catalog and enter your new File Share's UNC path (here we use \\localhost\writer as an example, where the manifest.xml file's path is \\localhost\writer\manifest.xml):


This will allow Word to see the Add-In manifest and use it for adding the Add-In:
