Fix PDF Search Not Working After Installing Adobe Reader DC
Question details
Users are unable to search for text inside PDF files using Windows Explorer and Outlook after upgrading their PDF reader software.
- Product
- Adobe Reader DC, Windows Search
- Device & OS
- Windows 7 32-bit
- Scenario
- Upgrading from Adobe Reader XI to Adobe Reader DC and attempting to search for document contents within local PST files or Exchange Server folders.
- Observed behavior
- PDF search functionality completely fails because the upgrade replaces the Adobe PDF iFilter with the standard Windows filter, preventing the system from indexing PDF file contents.
Ensure you have administrator privileges on your Windows 7 computer, as you will need elevated permissions to repair software installations and modify Windows Search indexing options.
Repair Adobe Reader DC and Rebuild the Windows Search Index
Re-registering the Adobe PDF iFilter by repairing the software and rebuilding the search index restores system-wide PDF search capabilities.
The upgrade process often breaks the existing iFilter registration. Running a software repair forces the system to correctly register the Adobe PDF iFilter, allowing Windows Search to read PDF contents again.
Open the Windows Control Panel, navigate to 'Programs and Features', select 'Adobe Acrobat Reader DC' from the list, and click 'Change' or 'Repair' to fix the installation.
Click the Start menu, type 'Indexing Options' in the search bar, and press Enter to launch the indexing settings.
Click the 'Advanced' button in the Indexing Options window. You may be prompted to provide administrator credentials.
Under the Troubleshooting section of the Advanced Options dialog, click the 'Rebuild' button to delete and recreate the index. Note that searching will be incomplete until this process finishes.
Verify PDF File Types and Outlook Indexing Settings
Check the advanced indexing options to ensure Windows is configured to index the actual contents of PDF files, not just their properties.

Frequently Asked Questions
Why did my PDF search stop working after upgrading to Adobe Reader DC?
Upgrading from an older version of Adobe Reader to Reader DC can sometimes overwrite or improperly unregister the Adobe PDF iFilter. This causes Windows to revert to a standard text filter that is incapable of parsing and reading the encoded text inside a PDF file.
Does this indexing issue also affect 64-bit Windows 7 systems?
Yes. While 64-bit systems historically required a separate 64-bit iFilter package, modern PDF readers include the iFilter automatically. However, the registration issue during an upgrade can happen on both 32-bit and 64-bit architectures, and the troubleshooting steps remain largely the same.
Can I search inside a PDF without fixing the Windows Search index?
Yes. The Windows Search index only affects searching for files from the Windows Explorer search bar or via Outlook. You can always open a PDF directly in your PDF software (like WPS Office or Adobe Reader) and use the native 'Find' function (Ctrl+F) to search its contents.
Why are my Outlook emails with PDF attachments not showing up in searches?
Outlook relies entirely on the Windows Search service to parse attachments. If the PDF iFilter is broken or if Outlook is excluded from the Windows Indexing Options, Outlook will not be able to scan or return search results based on the text inside attached PDF documents.
