Fix Missing Proofing Tools in Microsoft Word

If Microsoft Word says “Proofing tools are not installed” or the spelling and grammar checker is grayed out, the fix is to install the proofing tools component through the Office installer. This article walks you through the exact steps for Windows and Mac, explains why the issue happens, and answers common follow-up questions.

Why Proofing Tools Go Missing

Proofing tools include the spelling checker, grammar checker, thesaurus, hyphenation, and language-specific dictionaries. They are not always installed by default. During Office installation or a later update, the proofing tools component can be skipped, removed, or corrupted. Common triggers include:

• Choosing a “minimal” or “custom” install that omits proofing tools.
• Running a repair that only fixes the main program files, not the language packs.
• Installing a language pack after Word, but not enabling the proofing tools for that language.
• Corrupted user profile or registry entries after a failed update.

When this happens, Word may still open documents and let you type, but the spelling and grammar commands are unavailable, and you may see an error message when you press F7 or click “Spelling & Grammar.”

How to Check If Proofing Tools Are Installed

Before reinstalling anything, confirm whether the tools are actually missing. In Word on Windows:

1. Open Word and go to File > Options > Proofing.
2. Look for the “When correcting spelling and grammar in Word” section. If the checkboxes are grayed out, the tools are not installed.
3. Alternatively, press F7 to run a spelling check. If you see the error “Proofing tools are not installed,” they are missing.

On Mac, go to Tools > Spelling and Grammar. If the options are grayed out, the proofing tools are absent.

Fix 1: Repair Office from Control Panel (Windows)

The built-in repair tool is the first thing to try because it reinstalls missing components without a full uninstall. Steps:

1. Close all Office applications.
2. Open Control Panel > Programs and Features (or Settings > Apps on Windows 10/11).
3. Find Microsoft 365 or Microsoft Office in the list.
4. Click Change (or select it and click “Change”).
5. Choose Quick Repair first. This is faster and usually enough. If the problem persists, choose Online Repair, which downloads a fresh copy of Office.
6. Follow the prompts and restart your computer when done.

After the repair, open Word and test F7. If the error is gone, you are done.

Fix 2: Add the Proofing Tools Feature Manually

If a repair does not work, the proofing tools component may be set to “Not Available” in the Office installer. On Windows:

1. Open Control Panel > Programs and Features.
2. Select your Office product and click Change.
3. In the setup window, choose Add or Remove Features (or “Modify”).
4. Expand Office Shared Features (or “Office Tools”).
5. Find Proofing Tools and set it to Run from My Computer.
6. Click Continue and let the installer finish.

On Mac, the proofing tools are part of the main Office app; there is no separate component to add. If they are missing on Mac, the fix is to reinstall Word or update Office via the Microsoft AutoUpdate tool.

Fix 3: Install or Enable the Correct Language Pack

Proofing tools are language-specific. If you are typing in a language that does not have its proofing tools installed, Word will show the error. For example, if you type in French but only installed English proofing tools, the French checker will be missing.

To add a language:

1. Go to File > Options > Language in Word.
2. Under “Choose Editing Languages,” select the language you need and click Add.
3. If the proofing tools for that language are not installed, you will see a link to install them. Click it and follow the prompts.
4. After installation, restart Word.

Note that some languages (like English) have multiple variants (US, UK, Canadian). Make sure the variant you selected matches the dictionary you need.

Fix 4: Clear the Office Cache or Reinstall Office

If repair and manual feature addition fail, the problem may be a corrupted cache or a broken installation. Try these steps in order:

• Clear the Office cache: close all Office apps, then delete the contents of %LocalAppData%\Microsoft\Office\16.0\OfficeFileCache (the path may vary by version). Restart Word.
• Uninstall Office completely using the official Microsoft Support and Recovery Assistant, then reinstall from your Office account portal.
• On Mac, uninstall Word (move it to Trash) and reinstall from the App Store or your Microsoft account.

Reinstalling is a last resort because it takes time and may require you to re-enter your product key or sign in again, but it almost always resolves missing proofing tools.

Frequently Asked Questions

Why does Word say “Proofing tools are not installed” even after I reinstalled Office?

This usually happens when you reinstalled the same broken configuration. Make sure you run a full repair (Online Repair) rather than Quick Repair, and verify that the proofing tools feature is set to “Run from My Computer” during the repair. Also, check that the correct language pack is installed for your editing language.

Can I use the spelling checker without installing proofing tools?

No. The spelling and grammar checker is part of the proofing tools. Without them, Word cannot check spelling, grammar, or thesaurus. You can still use third-party add-ins or online spell checkers, but the built-in functionality will not work.

Will this fix affect my existing documents or formatting?

No. Repairing or adding proofing tools only affects the program files, not your documents. Your text, formatting, and custom dictionaries remain unchanged. It is still a good idea to back up important files before any Office repair, just in case.

What if I only see the error in one document?

If the error appears only in a specific document, the document may have language formatting set to a language without proofing tools. Select all text (Ctrl+A), go to Review > Language > Set Proofing Language, and choose a language with installed tools. If that does not help, copy the content into a new document.

Does this affect the grammar checker in Outlook or other Office apps?

Yes. Proofing tools are shared across Office applications. Fixing them in Word will also restore the spelling and grammar checker in Outlook, PowerPoint, and other Office programs that use them.
