Click Finish to acknowledge the successful configuration.

You will then receive the below Central Administration screen regarding configuring your SharePoint farm.  Because we have been configuring each service application one by one as needed (best practice) we will click cancel and proceed to activate the Office Web Apps services individually.

Enter the following details to complete the creation of the Word Viewing Service Application.  Ensure that you select “SharePoint Web Services System” from the Use existing application pool option.

You can now further provision the “Excel Services Application” and “PowerPoint Service Application” in the same manner following the above steps.  Please note that there isn’t a separate service application for OneNote.

Activating Office Web Apps

Depending on where you want the feature activated, you will venture to your Site Collection(s) and activate each one individually or you can utilise PowerShell to activate multiple site collections at once within a single script.

From within your SharePoint Site, click on Site Actions / Site Settings.

Under Site Collection Administration, click on Site Collection Features.

Navigate down the page until you find Office Web Apps and click on Activate.
