How to Fix Office 2016 Language Accessory Pack Proofing Issues
Question details
The user is unable to use proofing tools in Microsoft Word after installing an Office 2016 language accessory pack, typically due to an architecture mismatch.

- Product
- Microsoft Office 2016
- Device & OS
- Windows
- Scenario
- Setting up spelling and grammar proofing tools in Microsoft Word for a new language.
- Observed behavior
- Word continues to show the proofing tools as unavailable even after the language accessory pack has been installed.
Ensure you have administrator privileges on your computer and save any open documents before making modifications to your Office installation.
Verify Office Architecture and Reinstall the Matching Language Pack
Identify whether your Office installation is 32-bit or 64-bit so you can download and install the compatible language accessory pack.
A common cause for proofing tools failing to work is an architecture mismatch. Even if your Windows operating system is 64-bit, your Office installation might still be 32-bit. The language accessory pack must match the Office architecture, not the Windows OS architecture.
Open Microsoft Word and navigate to File > Account. Click on the 'About Word' button.
Look at the top line of the About Word dialog box to confirm if your specific Office installation is listed as 32-bit or 64-bit.
If you installed the wrong version previously, open the Windows Control Panel, go to Programs and Features, and uninstall the incorrect language accessory pack.
Visit the official Microsoft download page and select the language accessory pack that matches both your version (Office 2016) and your architecture (32-bit or 64-bit).
Run the newly downloaded installer. Once the installation is complete, restart Microsoft Word to activate the proofing tools.

Frequently Asked Questions
Why does Word say proofing tools are missing even after installation?
This usually happens when the installed language pack does not match the architecture (32-bit or 64-bit) of your Office application, or if a package for the wrong version of Office was downloaded.
How do I know if my Microsoft Office is 32-bit or 64-bit?
Open any Office app like Word, click on 'File', select 'Account', and click 'About Word'. The architecture will be listed at the end of the version string at the top of the dialog box.
Do I need to completely reinstall Microsoft Office to fix the language pack?
No, a full reinstallation is usually not required. You only need to uninstall the incorrect language accessory pack from your Control Panel, then download and install the version that matches your Office architecture.
