Office 365 Proofing Tools Offline Installer May 2026
Because Microsoft transitioned to Click-to-Run technology, creating an Office 365 offline proofing tool installer requires using the Office Deployment Tool (ODT) to download specific language files via a custom download.xml file. The process involves creating the configuration, running the download command to obtain the files, and then using the /configure command on the offline machine to install them. For a more direct option, users can download a full offline installer, which includes core proofing tools, through their Office.com account portal.
