For users needing Office 2021 Proofing Tools without a constant internet connection, the most reliable method is using the Office Deployment Tool (ODT) to create a dedicated offline installer. While older versions of Office provided standalone .exe downloads for proofing tools, Office 2021 (including LTSC and Retail) uses a "Click-to-Run" architecture that requires a more modern deployment approach. The Best Way to Get Office 2021 Proofing Tools Offline
The most effective and "official" way to handle offline proofing tool installation is through a custom configuration using the Office Deployment Tool. This method allows you to download only the lightweight proofing assets rather than a full language pack. 1. Download the Office Deployment Tool (ODT)
Start by downloading the free Office Deployment Tool from the Microsoft Download Center. Extract the contents (usually setup.exe and some sample XML files) into a folder on your computer, such as C:\ODT. 2. Create Your Offline Configuration File
Instead of using the default files, create a new text file named proofing.xml in your ODT folder. To download only the proofing tools for specific languages (e.g., German and Spanish), use the following XML structure:
Pro Tip: You can use the Office Customization Tool to build this file visually if you prefer not to edit XML manually. 3. Download the Files for Offline Use
Open Command Prompt as an administrator, navigate to your ODT folder, and run the following command to download the files to your local drive:setup.exe /download proofing.xml
Once finished, a new "Office" folder will appear containing the offline data. You can now move this entire ODT folder to any offline machine. 4. Install on the Offline Machine
On the target computer, run this command from the ODT folder to perform the installation:setup.exe /configure proofing.xml Alternative: Full Offline Installer (IMG/ISO)
If you already have a retail license, you can download a complete Offline Installer image from your Microsoft Account Portal. Log in and find your Office 2021 product.
Select Install, and in the "Choose a version" dropdown, select Offline installer.
This downloads a large .img file (usually ~4GB) that contains all proofing tools for your primary language and can be mounted like a virtual drive for installation without internet. Verification & Setup
After installation, open Word 2021 and navigate to File > Options > Language.
Under Office authoring languages and proofing, your new languages should now show a status of Proofing installed.
If it says "Proofing available," it may still require a small online update to activate the specific dictionary features.
