Microsoft Visual Studio 2010 Tools for Office Runtime 10.0.60917

Microsoft Visual Studio 2010 Tools for Office Runtime

The Visual Studio 2010 Tools for Office (VSTO) Runtime is a support framework that enables Office-based solutions built with Visual Studio to run on end-user machines. Distributed as an updated redistributable, this runtime is required to execute customizations and add-ins created with Visual Studio Tools for Office 4.0 and later development environments.

Purpose and Practical Applications

VSTO Runtime is intended for organizations and developers deploying Office-integrated solutions such as add-ins, automated document processing, custom task panes and form regions, and other managed-code extensions that interact with Word, Excel, PowerPoint, Outlook and other Office applications. It provides the hosting environment and integration glue between the .NET Framework and Office application object models so those solutions can execute reliably on client systems.

Key Features and Functionality

• Managed runtime hosting: Supplies the runtime components necessary to run .NET-based Office customizations developed with Visual Studio Tools for Office 4.0.
• Language configuration: The installer automatically configures VSTO to match the system language; additional language packs are available for multi-language environments.
• Compatibility update: This redistributable represents an update to previous VSTO runtime versions and is intended to support solutions built with Visual Studio 2013 and newer supported Visual Studio releases.

System Requirements and Prerequisites

Supported operating systems include Windows 7 SP1 through Windows 11, and corresponding Windows Server editions (Windows Server 2012, 2012 R2, 2016, 2019). On target machines, one of the following must be installed before the runtime: .NET Framework 3.5, .NET Framework 4, .NET Framework 4 Client Profile, or .NET Framework 4.5. Additionally, Office customizations built with this version of VSTO require a supported Microsoft Office installation such as Office 2013, 2016 or newer supported versions for Word, Excel, Outlook, PowerPoint, Visio, InfoPath and Project.

Deployment and Maintenance

The runtime is provided as a single installer (vstor_redist.exe) suitable for distribution alongside Office solutions. The package simplifies client deployment by centralizing the VSTO components required to run managed Office extensions; language packs are available for environments with multiple language settings or where language configuration changes after installation.
