Click-to-Run Update Support Tool for Office

The Click-to-Run Update Support Tool addresses a problem in Office 365 Home, Office 365 Personal, and Office Home & Student 2016 clients. This problem prevents the client from applying any Office updates.  

How it works

The Update Support Tool, available through Windows Updates, checks the client computer to identify the versions of the Click-to-Run client against the Client-to-Run service. If the version of the service and client do not match, the tool updates the Click-to-Run client to make sure that the client matches the service. A system restart is required for the tool to complete the update process. After completing this process, the Office client can resume to receive the update.
