Explanation:
Activate the Office Web Apps Feature for a site collection
The Office Web Apps Feature should be activated on every site collection for which any of the Web apps will be available. Typically, you activate the Office Web Apps Feature on a site collection during the deployment phase after you run setup and activate the services; however, in some cases, you can decide to later activate only on particular site collections and deactivate on other site collections.To activate the Office Web Apps Feature on a site collection on the Site collection features page
1. In a browser, in the SharePoint site, click Site Actions, and then click Site Settings.
2. On the Site Settings page, in Site Collection Administration, click Site Collection Features.
3. On the Features page, for Office Web Apps, click Activate.Source: http://technet.microsoft.com/en-us/library/ee837418.aspx
Configure the default open behavior for documents
In SharePoint, you can configure whether browser-enabled documents are opened in a client application or in the browser. By default, when Office Web Apps is installed, Office documents will open in the browser. You can override this setting using the SharePoint OpenInClient feature. The OpenInClient feature can be configured in Central Administration or by using the SPFeature cmdlet in Windows PowerShell.
How documents open in SharePoint varies depending on whether the OpenInClient feature is present, and either enabled or disabled:* If the OpenInClient feature is not present and Office Web Apps is not installed, documents will open in the client application (SharePoint default).
* If the OpenInClient feature is not present, Office Web Apps is installed and Office Web Apps service applications are activated, documents will open in the browser (Office Web Apps default).
* If the OpenInClient Feature is present and enabled, and Office Web Apps service applications are activated, documents will open in the client application.
* If the OpenInClient Feature is present and disabled, and Office Web Apps service applications are activated, documents in will open in the browser.To set the default open behavior for site collections by using Central Administration
1. In SharePoint Central Administration, click Site Actions, and then click Site Settings.
2. On the Site Settings page, under Site Collection Administration, click Site Collection Features.
3. On the Features page, for the Open Documents in Client Applications by Default feature, click Activate (OpenInClient Feature is enabled) to open documents in the client application. Click Deactivate (OpenInClient Feature is disabled) to open documents in the browser.Source: http://technet.microsoft.com/en-us/library/ee837425.aspx
