In plain English

Office Tool Plus is a Windows desktop application for installing, managing, and activating Microsoft Office products. It handles the full deployment process without requiring users to navigate Microsoft's official setup tools, which can be confusing for custom configurations. The tool covers Microsoft 365, Office versions from 2016 through 2024, and related Microsoft products like Visio and Project. You can choose exactly which applications to install, which language to download, and which update channel to pull from. Once installed, it can also modify an existing Office setup, letting you add or remove individual applications without reinstalling everything from scratch. Activation support is built in, covering the standard online activation path, phone activation, and KMS activation for volume licensing environments. The tool also manages licenses and update channels directly, so you can switch Office between different release tracks, or upgrade and downgrade versions, without uninstalling and reinstalling. A few extra utilities are included: forcing Office to uninstall when the normal removal process fails (covering versions from 2003 onward), converting Office documents using Office's own COM interface, and fixing common Office problems by resetting settings. You can also package a complete Office installer into an ISO file, with options for a silent installation preset. The GitHub repository specifically hosts the localization files for the project, which explains the translator credits in the README. The actual application is written in C# and is available for download at otp.landian.vip. A quick PowerShell command is provided for those who prefer to skip the website and download directly from the terminal.
