Troubleshooting the Adobe Reader Spelling Dictionary Pack: Fixes & Tips

How to Install the Adobe Reader Spelling Dictionary Pack (Step-by-Step)

Before you start

• Ensure you have Adobe Acrobat Reader DC installed and closed.
• Download the correct Spelling Dictionary Pack file for your language and Reader version (usually a .cmap or .dic/.aff bundle or an installer package from a trusted source).

1. Locate the dictionary files or installer

• If you downloaded an installer (EXE/MSI on Windows or PKG on macOS), use that.
• If you downloaded dictionary files, note their folder path (you’ll copy them into Reader’s dictionary location).

2. Install using an installer package (recommended)

• Windows: right-click the installer → Run as administrator → follow prompts. When finished, restart Adobe Reader.
• macOS: open the PKG → follow installer prompts → restart Adobe Reader.

3. Manual installation (if no installer)

• Windows:
  1. Open File Explorer and navigate to:
     C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\Resource\Spelling\ or
     C:\Program Files\Adobe\Acrobat Reader DC\Reader\Resource\Spelling\ (depending on your install).
  2. Copy the dictionary files (.dic/.aff or language folder) into that Spelling folder.
• macOS:
  1. In Finder, go to Applications → Adobe Acrobat Reader DC → Show Package Contents → Contents → Resources → Spelling.
  2. Copy the dictionary files or language folder into that Spelling folder.

4. Set the language in Adobe Reader

1. Open Adobe Reader.
2. Go to Edit → Preferences (Windows) or Adobe Reader → Preferences (macOS).
3. Select “Language” from the left pane.
4. Under “Application Language” or “Choose at launch,” ensure the desired language is available/selected.
5. Close and reopen Reader if needed.

5. Verify the dictionary is active

• Open a PDF with selectable text and use Tools → Spelling → Check Spelling (or press the spell-check command if available).
• Misspelled words should now be detected according to the newly installed dictionary language.

6. Troubleshooting

• Not detected: confirm files are in the correct Spelling folder and compatible with your Reader version.
• Permission errors: on Windows run the copy step as administrator; on macOS authenticate when copying into the app package.
• Version mismatch: ensure the dictionary pack specifically supports Acrobat Reader DC and your OS (32-bit vs 64-bit).
• If problems persist, reinstall Adobe Reader and then re-add the dictionary.
