Office 365 Proofing Tools Offline Installer __hot__ May 2026

For Microsoft 365 (formerly Office 365), there is no single standalone "proofing tools" exe file for offline use.

The ODT is a command-line utility used to download and deploy Microsoft 365 Apps to your local environment.

To download just the proofing tools for a specific language, you need a custom configuration file.

Open Notepad and paste the following code (example for Spanish):

Change es-es to your desired Language ID (e.g., fr-fr for French, de-de for German). Save this file as proofing.xml in your C:\ODT folder. Step 3: Download the Proofing Tools (Requires Internet)

This step fetches the actual installer files from Microsoft's servers to your local folder so you can use them offline later. Open Command Prompt as an Administrator. Navigate to your folder: cd C:\ODT Run the download command:setup.exe /download proofing.xml

Wait for the process to finish. A new Office folder will appear in C:\ODT containing the offline data. Step 4: Install Offline
