2. Installation Method

Quick install (user) - Word Desktop / Word Online / Word for Mac

2. Go to Insert > Add-ins > Get Add-ins (the "Office Add-ins" dialog opens).

1. Confirm any permission/trust prompts.

2. Launch the add-in via Insert > Add-ins > My Add-ins (or the new ribbon button/task pane).

Admin deployment - Microsoft 365 (Centralized deployment)

1. Sign in as a Global admin at https://admin.microsoft.com.

2. Search for Add-ins / Integrated apps (or find Settings → Integrated apps / Add-ins).

3. Choose Deploy Add-in (or Upload add-in) → upload manifest.xml or provide the manifest URL.

4. Assign to users/groups or the whole organization → complete deployment.

5. Note: rollout may take minutes to several hours for all users.

1. Upload manifest.xml to the tenant App Catalog (Apps for Office).

2. Users find the add-in under Insert > Add-ins > My Add-ins > My Organization.

3. Verify & Open the add-in

• Open Word → Insert > Add-ins > My Add-ins → select the add-in.

• Expected result: add-in opens in a task pane or appears on the ribbon per manifest.

4. Update / Uninstall

• Update: re-upload updated manifest (user-side remove + add or replace via admin center).

• Uninstall (user): Insert > Add-ins > My Add-ins → find the add-in → remove/uninstall.

Troubleshooting (common issues)

• “Upload My Add-in” not visible — ensure modern Office (Microsoft 365 / Office 2016+); use Word Online as fallback.

• Manifest download blocked — try PowerShell/curl or check network proxies.

• Add-in not listed after deploy — sign out/sign in, wait for propagation, confirm assignment in admin center.

• Add-in fails to load — check manifest validity, HTTPS accessibility of resources, and browser/devtools console for errors.

• Permissions prompt — verify the manifest's requested permissions and accept if expected.

Requirements & notes

• Supported clients: Word for Microsoft 365 (Windows / Mac), Word Online; some legacy Office builds may not support custom add-ins.

• Manifest and web endpoints must be served over HTTPS with valid certificates.

• If you need the manifest validated, run it through an XML linter or the Office Add-in validator before deployment.
