Determine why the SharePoint OpenDocument Class ActiveX add-on is missing and how to restore document integration in Internet Explorer.
- Product
- SharePoint, Internet Explorer, Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to open SharePoint documents using Internet Explorer alongside Reader DC or Acrobat XI.
- Observed behavior
- The SharePoint OpenDocument Class ActiveX add-on appears on some systems but is completely missing from the add-on list on others, preventing activation.
Verify the exact versions of SharePoint, Internet Explorer, and your Adobe application, ensuring you know whether your system is using 32-bit or 64-bit components.
Match Application Architectures
Ensure that your browser, Office components, and PDF reader architectures match, as ActiveX add-ons require consistent 32-bit or 64-bit environments to load.
A common reason the SharePoint OpenDocument Class add-on fails to appear is an architecture mismatch. If you are running a 64-bit version of Internet Explorer but a 32-bit version of Office or Adobe Reader, the add-on will not register or display properly.
Open Internet Explorer, click the Settings gear icon, and select 'About Internet Explorer' to verify if you are running the 32-bit or 64-bit version.
Open Reader DC or Acrobat XI, go to 'Help' > 'About Adobe Acrobat', and check the architecture details.
If there is a mismatch, uninstall the conflicting software and download the version (either 32-bit or 64-bit) that matches your primary workflow environment.
Repair SharePoint or Office Integration Components
Repair the Office installation to properly register the SharePoint OpenDocument Class component in the Windows registry.

Frequently Asked Questions
Why is the SharePoint OpenDocument Class missing from Manage Add-ons?
It is typically missing because the necessary SharePoint or Office integration components are either not installed, corrupted, or there is an architecture mismatch (e.g., 32-bit vs. 64-bit) between the browser and the application.
Can I manually add the ActiveX control to Internet Explorer?
No, you cannot simply enable it if it is missing from the list. The component must be properly installed and registered in the Windows registry by repairing or installing compatible integration components.
Does this ActiveX issue affect modern browsers like Chrome or Edge?
No, ActiveX is an obsolete technology exclusive to Internet Explorer. Modern browsers handle SharePoint documents using different integration methods and do not require this add-on.
Is it safe to continue using Acrobat XI and Internet Explorer?
No. Both Adobe Acrobat XI and Internet Explorer have reached end-of-life and no longer receive security updates. Transitioning to supported, modern software is highly recommended.
