Office 2021 Proofing Tools Offline Installer

Finding a true, standalone "offline installer" specifically for Office 2021 Proofing Tools is significantly harder than it was for previous versions (like 2013 or 2016). Microsoft has moved away from downloadable .exe language packs for retail versions, pushing users toward the "Language Accessory Pack" model or Configuration Profiles.

Verdict: It is possible to install proofing tools offline, but it requires technical effort (using the Office Deployment Tool). The "easy" one-click offline installers largely no longer exist officially.
