How to Fix Adobe Send Add-in Missing in Office 2019 with Acrobat X
Product
Microsoft Office 2019 and Adobe Acrobat X
Device & OS
not provided
Scenario
Setting up a new computer and attempting to migrate an older version of Adobe Acrobat to integrate with a newer version of Office.
Observed behavior
The Adobe Send add-in does not appear in Office 2019. Manually copying DLL and executable files from the old computer fails to restore the functionality.
Before you start

Ensure you have the official installation media or setup files for Adobe Acrobat X, as manually copying system files will not properly register necessary COM add-ins in Windows.

Solution 1Recommended

Verify and Enable the Add-in via Office COM Settings

Check if the Acrobat add-in is installed but currently disabled by Office 2019.

Sometimes Office successfully installs the add-in but automatically disables it due to perceived performance issues or version mismatches. Checking the COM Add-ins menu is the fastest way to verify its status.

1
Open Office Options

Launch Word, Excel, or PowerPoint 2019. Click on the 'File' tab in the top-left corner, then select 'Options' at the bottom of the left sidebar.

2
Navigate to Add-ins

In the Options dialog box, click on 'Add-ins' in the left pane.

3
Manage COM Add-ins

At the bottom of the window, find the 'Manage' dropdown menu. Select 'COM Add-ins' from the list and click the 'Go...' button.

4
Enable Adobe Send

Look for the Acrobat or Adobe Send add-in in the list. If it is unchecked, check the box and click 'OK' to enable it.

Verify and Enable the Add-in via Office COM Settings
Compatibility Warning: Acrobat X is significantly older than Office 2019, which may result in permanent compatibility issues even if the add-in is manually enabled.

Frequently Asked Questions

Why doesn't copying DLL files install my Office add-in?

Copying DLL files manually skips the critical Windows Registry entries required for Office to recognize and load the add-in. Software must be installed via its official setup executable to properly register COM add-ins.

Is Adobe Acrobat X compatible with Microsoft Office 2019?

Generally, no. Acrobat X is a legacy product released well before Office 2019. This massive age gap typically causes integration issues, missing ribbon tabs, or permanently disabled add-ins in newer Office versions.

Where can I manage disabled add-ins in Office 2019?

You can manage add-ins by opening your Office application (like Word or Excel), navigating to File > Options > Add-ins, selecting 'COM Add-ins' from the Manage dropdown menu at the bottom, and clicking 'Go'.

What should I do if my Adobe Send add-in cannot be enabled?

If the add-in remains unavailable due to compatibility issues, your best options are to upgrade to a newer, supported version of Adobe Acrobat, or use an alternative web-based file-sharing service to distribute your exported PDFs.
