Support for running Office 2013 side-by-side with existing Office installations

Click-to-Run is a Microsoft streaming and virtualization technology that reduces the time that is required to install Office. It also provides an isolated environment that allows users to run the latest version of Office side-by-side with an earlier version of Office on the same computer. When installed by using Click-to-Run, Office products can still run macros and interact with the other Office solutions that are installed on the computer. The Office Telemetry features also work with Office products that are installed by using Click-to-Run.

Click-to-Run plays an important role in the modern Office compatibility process by allowing users to pilot Office products without giving up their current environment. This safety net helps keep users productive while reducing their fear of change. Any time that a document or solution doesn't work correctly in an Office product, the user can open that file in the earlier version of Office and continue to work.

You can learn more about how to install Office products by using Click-to-Run in Click-to-Run overview. See Phase 3: Validate that Office files work to learn more about how Click-to-Run is used during the Validate phase in the modern Office compatibility process.
