Repair the Acrobat Installation

Use the built-in repair tool to fix corrupted installation files or broken Windows Explorer shell extensions that cause the context menu to malfunction.

When Acrobat is updated or when Windows system changes occur, the registry keys responsible for the right-click context menu can become unlinked. Repairing the installation restores these default configurations.

Open the Adobe Acrobat 2017 application from your Windows Start menu or desktop shortcut.

2
Access the Repair Tool

Click on the 'Help' menu located on the top toolbar of the application window.

3
Run Installation Repair

Select 'Repair Installation' from the dropdown list. Confirm any administrator prompts that appear.

4
Restart the Computer

Wait for the automated repair process to finish, and then restart your computer to apply the registry changes.

5
Test the Feature

Open Windows Explorer, highlight multiple PDF files, right-click, and select the Combine Files command to verify it opens the tool correctly.

Frequently Asked Questions

Why does the Windows Explorer context menu open the Acrobat app instead of the Combine tool?

This behavior typically occurs when Acrobat's registry keys or shell extensions for Windows Explorer become corrupted or unlinked. Running the 'Repair Installation' tool from the Help menu usually restores the correct functionality.

Does the Combine Files context menu work on Windows 10 and 11?

Yes, Adobe Acrobat is designed to integrate its Combine Files feature directly into the Windows Explorer context menu on modern Windows versions, provided the application is installed correctly.

What should I do if repairing the Acrobat installation does not solve the problem?

If repairing does not work, you may need to completely uninstall the software, restart your PC, and perform a clean reinstallation using the latest installer available from your Adobe account.
