Office 365 Proofing Tools Offline Installer – Write-Up

Method 2: Use Existing Office Installation Cache

If Office 365 is already installed, proofing tools for added languages are cached here:

You can copy this folder, but this is not a reliable installer — it may miss registry entries.

Available offline installation options

1. Language Accessory Pack (Microsoft 365 / Office)

   • Official Microsoft support page lists LAPs per language with download links for 32/64-bit installers.
   • LAP includes display, help, and proofing tools depending on language; proofing status appears in Office language settings after install.

2. Microsoft Office Proofing Tools (standalone)

   • Microsoft Download Center has standalone Proofing Tools installers for legacy Office releases (e.g., "Microsoft Office Proofing Tools 2016" with per-language EXE files).
   • These are small offline EXE packages (~12 MB for English 2016) that install proofing components without a full Office reinstallation.

3. Office offline installer + language selection

   • For Microsoft 365 you can download the Office offline installer (IMG) from your account portal, then install and add languages/proofing via Office > File > Options > Language.
   • Useful when network reliability prevents web-based install; proofing tools may still require LAP or additional language package installs.

Recommendations

• For Microsoft 365: use the Language Accessory Pack for Microsoft 365 offline installers for desired languages.
• For Office 2016/2019: use the version-specific Proofing Tools package from Microsoft Download Center.
• Match installer architecture (x86/x64) to your Office installation to avoid issues.
• Keep a copy of the downloaded offline installers for offline deployments or imaging.

If you want, I can:

• Provide direct filenames and exact download links for specific languages and architectures (specify language and Office version).

Executive Summary

Office 365 Proofing Tools allow users to edit documents in languages different from the base installation language of Office. While modern versions of Office 365 (Click-to-Run) handle most language additions via online streaming, administrators and users in restricted environments often require an Offline Installer.

This report details the method to generate a complete offline installation package for Proofing Tools using the official Microsoft Office Deployment Tool (ODT).

The Problem with Standard Installation

By default, when you try to use a language not installed on your Office 365 suite, Microsoft 365 apps will prompt you to download the proofing tools from Microsoft servers. This "click-to-run" method requires:

• An active internet connection for each device.
• Administrative rights for each installation.
• Sufficient bandwidth, as some language packs exceed 200 MB.
• Time—waiting for downloads on multiple machines is inefficient.

For IT administrators managing 50 or 500 computers, this is a nightmare.
