To get the best offline installer for Office 2021 proofing tools, you generally have two main paths depending on whether you are an individual user or managing a volume license for an organization.
The "best" method is typically using the Office Deployment Tool (ODT), as it allows you to download specific language packs (which include proofing tools) for offline use without re-downloading the entire Office suite. 1. The Pro Method: Office Deployment Tool (ODT)
This is the most reliable way to create a dedicated offline installer for specific proofing tools.
Download the Tool: Get the Office Deployment Tool from the official Microsoft Download Center.
Create a Configuration File: Use the Office Customization Tool to select "Office LTSC 2021" and then pick only the Additional Languages you need. This will bundle the proofing tools for those languages.
Run the Download Command: Open Command Prompt as Administrator and run:setup.exe /download configuration.xml
Offline Install: Once downloaded, you can move these files to any offline PC and run:setup.exe /configure configuration.xml 2. The Standard Method: Language Accessory Packs
If you just need to add a language to an existing installation, Microsoft provides Language Accessory Packs.
Check Settings: Open any Office app (like Word) and go to File > Options > Language.
Install Online: If you have a temporary connection, clicking "Add a Language" will download the necessary proofing tools automatically.
Manual Download: For a true offline installer, visit the Language Accessory Pack for Office page, select "Office 2021," and choose your language to download the .exe installer. 3. The "Full Suite" Method: Account Portal
If you haven't installed Office yet and want everything (including proofing tools) in one offline file: Sign in to your Microsoft Account Dashboard. Select Install next to your Office 2021 product.
In the window that appears, select Offline installer from the version drop-down.
This downloads a large .img or .iso file containing the full setup and all standard proofing tools for your selected primary language.
Pro Tip: Proofing tools include the spell checker, grammar checker, thesaurus, and hyphenators. If you are using Office LTSC 2021, always ensure your ODT version is up to date to avoid compatibility errors during the offline extraction process. Use the Office offline installer - Microsoft Support
The most effective "offline" method for installing Office 2021 proofing tools is using the Microsoft Office Deployment Tool (ODT). While a one-time internet connection is required to download the initial files, this method allows you to bundle specific proofing tools into a single local installer for subsequent offline deployments. Recommended Method: Office Deployment Tool (ODT) office 2021 proofing tools offline installer best
The ODT is preferred for offline use because it lets you specify "ProofingTools" as a product ID in a configuration file, which results in a significantly smaller download than full language packs. Steps to Create an Offline Proofing Tools Installer:
Download the ODT: Get the latest version from the Official Microsoft Download Center.
Create a Configuration File: Use the Office Customization Tool (OCT) to generate a configuration.xml file. Set the Product ID to ProofingTools. Add the Language IDs you need (e.g., en-us, es-es).
Download Files for Offline Use: Open Command Prompt as an administrator in your ODT folder and run:setup.exe /download configuration.xml
This creates an "Office" folder containing all necessary data for those specific proofing tools.
Install Offline: Move the ODT and your downloaded "Office" folder to the target machine. Run:setup.exe /configure configuration.xml Alternative: Language Accessory Packs
If you prefer a simpler executable installer, you can download Language Accessory Packs. These include both the display language and the required proofing tools. Source: Visit the Microsoft Support Page.
Process: Select Office 2021, choose your language, and download the 32-bit or 64-bit installer.
Pros/Cons: Easier to use but installs the full language interface, which may be more than you need if you only want spellcheck. Direct ISO/IMG Downloads

This guide breaks down the most efficient way to build your own offline installer using official Microsoft tools. 1. The Challenge with Office 2021 Proofing Tools
Unlike older versions (like Office 2016) which had dedicated installers, Office 2021 bundles proofing tools within Language Accessory Packs.
