Allow Installation and Manage Acrobat Office Integrations

Understand the purpose of these system changes and how to manage the newly added Microsoft Office and Windows Explorer integrations.

Adobe Acrobat has included Microsoft Office and Windows Explorer integrations for approximately 20 years. These changes are intentional and necessary for features like seamless PDF creation, file conversion, and right-click context menu actions.

The installation takes a significant amount of time because it must register multiple add-ins, context menu items, and background services across various system components.

1
Complete the installation

Wait for the Acrobat installation progress bar to finish completely. Do not interrupt the process, as doing so can cause registry errors or broken Office add-ins.

2
Review installed Office Add-ins

Open Microsoft Word or Excel, navigate to 'File' > 'Options' > 'Add-ins' to view the newly installed Acrobat PDFMaker COM Add-in.

3
Disable unwanted integrations

If you prefer that Acrobat does not integrate with Office, select 'COM Add-ins' from the Manage drop-down at the bottom of the Add-ins window, click 'Go', and uncheck the 'Acrobat PDFMaker Office COM Addin'.

Frequently Asked Questions

Can I install Adobe Acrobat without the Microsoft Office add-ins?

Yes, during a custom installation of Acrobat, you can expand the 'Create Adobe PDF' feature tree and set the Microsoft Office plugins to 'This feature will not be available'. IT admins can also disable them prior to deployment using the Adobe Customization Wizard.

Why is Microsoft Word running slowly after installing Adobe Acrobat?

The Acrobat PDFMaker add-in loads automatically when you start Microsoft Word, which can increase the application's startup time and consume additional memory. You can manually disable this add-in in Word's Add-ins options if you experience significant performance issues.

Is it safe that Acrobat changes my Windows Explorer context menus?

Yes, it is completely safe. Acrobat adds options like 'Convert to Adobe PDF' to your right-click menu in Windows Explorer for your convenience. This is a standard integration feature that has been part of the Adobe Acrobat software for decades.
