This section discusses some considerations that you should take into account before you revert to an earlier version of an Office Click-to-Run installation.
 

Consider the severity of the issue

Before you decide to revert to an earlier version of an Office Click-to-Run installation, you should weigh the severity of the issue that you're experiencing against the benefits of having the security, performance, and reliability improvements that are included in the latest Click-to-Run update.
 

Revert to the previous version of Office Click-to-Run

Follow these steps to revert to the previous version of Office Click-to-Run.

Important The Office Click-to-Run installation is streamed from the Internet. Make sure that your connection to the Internet is reliable and persistent.
 

Step 1: Set a reminder to enable automatic updates at a future date

Before you revert an Office Click-to-Run installation, you should disable automatic updates. To make sure that you don't miss future updates, set a reminder to manually check for future versions. When a new version becomes available, and if the new version doesn't exhibit the same issue that you experienced earlier, you should re-enable automatic updates.

Create a reminder to re-enable automatic updates. You can do this in Microsoft Outlook, on Outlook.com, or by using another application that has a calendar.

   </Configuration>
