Fix 'No Previewer Installed' Error in Outlook Quickly

If you’re encountering the ‘This file cannot be previewed because there is no previewer installed’ error in Outlook, you’re likely unable to view attachments directly within the email client. This can be frustrating, especially when you need quick access to files like PDFs, Word documents, or Excel sheets. Fortunately, resolving this issue involves a few straightforward steps that can restore your ability to preview attachments seamlessly. This guide will walk you through what you need to do, from understanding the cause to fixing it efficiently, ensuring you can get back to your workflow without unnecessary hassle.

What You’ll Need

  • Access to your computer with administrative rights (recommended but not always necessary)
  • Microsoft Outlook installed and updated
  • Internet connection (for updates and downloads)
  • Optional: Office apps installed (Word, Excel, PowerPoint) depending on the file types you preview

Step-by-Step

  1. Open Microsoft Outlook on your computer.
  2. Check the attachment to see if the preview error appears. Try clicking on the attachment again to confirm the issue.
  3. Update Microsoft Office and Outlook:
    • Go to the ‘File’ tab in Outlook.
    • Select ‘Office Account’ or ‘Account.’

      • >

    • Click on ‘Update Options’ and choose ‘Update Now.’
    • Allow the update process to complete, then restart Outlook and check if the preview works.
  4. Verify the Preview Handler Add-ins:
    • Click on ‘File’ > ‘Options’ > ‘Add-ins.’
    • At the bottom, set ‘Manage’ to ‘COM Add-ins’ and click ‘Go.’
    • Ensure that relevant preview handlers like ‘Microsoft Outlook Previewer’ or third-party handlers are enabled.
    • If disabled, check the box next to them and click ‘OK.’
  5. Repair Office Installation:
    • Close all Office applications.
    • Go to ‘Control Panel’ > ‘Programs’ > ‘Programs and Features.’
    • Find ‘Microsoft Office’ in the list, right-click, and select ‘Change.’
    • Choose ‘Online Repair’ or ‘Quick Repair’ and follow the prompts.
    • Once repaired, reopen Outlook and test the attachment preview.
  6. Reset the Outlook Previewer Settings:
    • Close Outlook.
    • Open the Registry Editor by typing ‘regedit’ in the Windows search box.
    • Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Office\\Outlook\PreviewHandlers
    • Backup the registry key before making changes.
    • If the relevant previewer keys are missing or corrupted, you can delete or recreate them following Microsoft support guidelines.
    • Restart Outlook and check if the preview feature is restored.
  7. Check Group Policy Settings:
    • Press Windows + R, type ‘gpedit.msc’, and press Enter.
    • Navigate to: User Configuration > Administrative Templates > Microsoft Outlook > Outlook Options > Preferences > Attachment Handling.
    • Ensure that the ‘Turn off Attachment Preview’ setting is disabled.
    • If changed, apply the setting, restart Outlook, and test the preview feature again.
  8. Install or Reinstall Necessary Preview Handlers:
    • If specific file types (like PDFs or images) won’t preview, ensure the appropriate preview handlers are installed.
    • Download and install the latest version of Adobe Acrobat Reader for PDFs, or the latest Office updates for Word, Excel, and PowerPoint previewers.

Common Mistakes

  • Skipping Office updates—outdated software can cause preview issues.
  • Disabling necessary add-ins or preview handlers without understanding their function.
  • Modifying registry keys incorrectly, which can cause further issues.
  • Ignoring the need for administrative rights during repair or updates.
  • Not restarting Outlook or the computer after making changes, which prevents updates from taking effect.

Tips

  • Always back up your registry before making changes to avoid accidental data loss.
  • Keep your Office and Outlook software up to date to prevent compatibility issues.
  • Use the ‘Diagnose’ feature in Office if available, which can automatically detect and fix common problems.
  • Verify that your Windows user account has the necessary permissions to modify Outlook settings and registry entries.
  • Clear Outlook cache: sometimes, cached data causes preview errors. To do this, close Outlook, then delete files in the %localappdata%\Microsoft\Outlook folder.
  • Consult IT support if you’re in a managed environment, as group policies may override local settings.

Troubleshooting

If the above steps don’t resolve the ‘no previewer installed’ error, try these additional troubleshooting tips:

  • Test with different file types: Determine if the issue is specific to certain file types or universal. If only one file type fails, focus on its specific preview handler.
  • Disable third-party add-ins: Sometimes, third-party add-ins interfere with Outlook’s previewer. Start Outlook in Safe Mode by holding the Ctrl key while launching Outlook or typing ‘outlook.exe /safe’ in the Run dialog. If previews work in Safe Mode, disable add-ins one by one to identify the culprit.
  • Check for Windows updates: Ensure your operating system is fully updated, as updates often include fixes for compatibility issues.
  • Reinstall Office: As a last resort, uninstall and reinstall Microsoft Office to resolve corrupted files or settings.
  • Use Microsoft Support and Recovery Assistant: Download and run this tool from Microsoft, which can diagnose and fix Office issues automatically.

Following these steps should help you resolve the ‘no previewer installed’ error in Outlook, restoring your ability to preview attachments directly within the application. If problems persist, contacting Microsoft Support may be necessary for advanced troubleshooting.
