How to Fix Combine Files from Windows Explorer Not Working in Acrobat 2017
Question details
The user is unable to use the Combine Files tool directly from the Windows Explorer context menu, as it simply opens the Acrobat application.

- Product
- Adobe Acrobat 2017
- Device & OS
- Windows
- Scenario
- Selecting multiple PDF documents in Windows Explorer and attempting to combine them into a single file via the right-click menu.
- Observed behavior
- Windows Explorer launches the main Acrobat application instead of opening the specific Combine Files tool. The tool only functions correctly if Acrobat is already running in the background.
Ensure you have saved all open PDF documents and completely closed out of any running instances of Adobe Acrobat before attempting to run the software repair tool.
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.
Click on the 'Help' menu located on the top toolbar of the application window.
Select 'Repair Installation' from the dropdown list. Confirm any administrator prompts that appear.
Wait for the automated repair process to finish, and then restart your computer to apply the registry changes.
Open Windows Explorer, highlight multiple PDF files, right-click, and select the Combine Files command to verify it opens the tool correctly.

Verify File Integrity by Testing Different PDFs
Determine if the issue is caused by specific corrupted PDF files or document security restrictions rather than the application itself.

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.
