If you need a single, executable offline installer for one specific language (e.g., French, German, Spanish, Arabic), this is the gold standard.
The best way to get an offline installer for Office 2021 proofing tools is by using the Office Deployment Tool (ODT). While Microsoft does not provide a standalone "offline EXE" for proofing tools alone, you can use the ODT to download only the proofing components for your required languages to a local folder. Method 1: Using the Office Deployment Tool (Recommended)
This method allows you to download proofing tools once and install them on multiple machines without an internet connection.
Download ODT: Get the latest Office Deployment Tool and extract setup.exe to a folder (e.g., C:\ODT).
Create Configuration XML: Use a text editor to create a file named proofing.xml in that same folder with the following content (replace de-de and es-es with your needed Language IDs):
<Configuration> <Add OfficeClientEdition="64"> <Product ID="ProofingTools"> <Language ID="de-de" /> <Language ID="es-es" /> Product> Add> Configuration> Use code with caution. Copied to clipboard
Download Files: Open an elevated Command Prompt, navigate to your folder, and run:setup.exe /download proofing.xmlThis downloads the necessary files to a subfolder named Office.
Install Offline: To install on any machine from those files, run:setup.exe /configure proofing.xml. Method 2: Language Accessory Packs
If you have internet access on the target machine, you can download a Language Accessory Pack, which includes proofing tools. Go to the Language Accessory Pack for Office page. Select Office 2021 from the tabs. office 2021 proofing tools offline installer best
