What is this?
Office Tool Plus is a free tool for deploying and managing Microsoft Office — it downloads, installs, modifies and activates Office products, and bundles repair and cleanup utilities.
Is it a separate app, or part of Office itself?
A separate Windows app, not Office itself — it manages Microsoft products: Microsoft 365, Office 2016-2024, Visio 2016-2024 and Online Plan 2, and Project 2016-2024 with Online Desktop Client.
How do I get it running?
Download it from the project site or docs page, or grab it with the PowerShell command from the README's quick start, then pick your products, language and apps and install.
Do I need Office already installed to use it?
No — the tool downloads Office itself, in any language and from any update channel, so a clean Windows PC is enough to get started.
Will it run on macOS or Linux?
No — it's a Windows-only desktop tool; deploying the Windows versions of Office on a Mac isn't something it covers.
Can it change an Office installation I already have?
Yes — it can add or remove apps from an existing install in one step, switch the update channel, and upgrade or downgrade Office without reinstalling it.
Does it handle Office activation?
Yes — online, phone and KMS activation are supported, plus management of licenses, product keys and KMS settings.
What if Office is broken and refuses to uninstall?
It can force-remove Office anywhere from 2003 to the latest version when a normal uninstall fails, and built-in utilities can reset settings and fix common Office problems.
Can it build an offline installer for other machines?
Yes — it creates Office ISOs with a default or a silent installation config, handy for offline or repeated deployments.
