Sharepoint 2010 + Office Web Apps - Viewing Word File in Browser Get error but i can Editcan viewing by editing it

The error messages might include, but are not limited to, the following:

·         Unable to process the request.

·         An unexpected error has occurred.

·         PowerPoint Web App encountered an error. Please try again.

·         Word Web App cannot open this document due to an unknown error. If the problem persists, try opening the file in Microsoft Word.

·         OneNote Web App cannot open this notebook because the Office Web Apps Feature isn't activated on this site collection. Try opening the file in Microsoft OneNote.

·         The file that you selected could not be found. Check the spelling of file name and verify that the location is correct. Make sure that the file has not been renamed, moved, or deleted.

These errors might occur for one or more of the following reasons:

·         The SharePoint administrator has run Office Web Apps Setup, which configures the default open behavior for SharePoint to open Microsoft Word, Excel, PowerPoint, and OneNote documents in the browser by using their associated Web application. However, the SharePoint administrator has not yet started the services, created the service applications, and activated the Office Web Apps feature.

·         The Office Web Apps services are not started on the Web front-end server.

·         The Office Web Apps service applications and proxies have not been created.

·         The Office Web Apps service applications proxies are not associated with the proxy group of the Web application that the site collection belongs to.

·         There might be a problem with the permissions for the service account that is used to run the Web application or one of the Office Web Apps services: Excel Calculation Services, PowerPoint Service, or Word Viewing Service. The Web application and service applications must have the appropriate permissions to access the content databases and the configuration database.

To resolve these errors, apply the following solutions:

·         The SharePoint administrator can avoid end users' seeing error messages while he or she finishes additional deployment tasks to deploy Office Web Apps on a live production server. We recommended that you enable the OpenInClient feature on existing site collections before you run Setup. For more information, see Configure the default open behavior for browser-enabled documents (Office Web Apps).

·         Activate the Office Web Apps feature for the site collection. For information about how to activate the Office Web Apps feature for a site collection, see Activate the Office Web Apps feature in Deploy Office Web Apps (Installed on SharePoint 2010 Products).

·         Verify that the services have been created and check the status of the services on the servers in the farm by doing the following:

1.       On the Central Administration Web site, in Application Management, click Manage services on server.

2.       On the Services on Server page, do the following:

1.       In the list of services on the selected server, verify that Excel Calculation Services, PowerPoint Service, and Word Viewing Service exist and are started. If a service is not started, click Start.

2.       Click the Server button at the top, click Change Server, and then in the Select Server dialog box, click a different server name.

3.       Repeat these steps until you have verified that the services exist and are started on all servers in the farm.

·         Verify that the Office Web Apps service applications and proxies have been created by doing the following:

1.       On the Central Administration Web site, in Application Management, click Manage service applications.

2.       On the Manage Service Applications page, verify that there the following kinds of service applications exist:

§  Excel Services Application Web service application

§  PowerPoint service application

§  Word Viewing service application

Verify that the service applications have been created. For information about how to create service applications, see Create the service applications and the service application proxies in Deploy Office Web Apps (Installed on SharePoint 2010 Products).

·         Verify that the Office Web Apps service applications and proxies are associated with the proxy group of the Web application that the site collection belongs to by doing the following:

1.       On the Central Administration Web site, in Application Management, click Manage web applications.

2.       On the Web Applications Management page, select the Web applications that the site collection belongs to, and then click Service Connections.

3.       On the Configure Service Application Associations page, verify that the following kinds of service application proxies are associated with the Web application:

§  Excel Services Application Web service application proxy

§  PowerPoint service application proxy

§  Word Viewing service application proxy

For information about how to add service application connections to a Web application, see Add or remove a service application connection to a Web application (SharePoint Server 2010) or Add or remove a service application connection to a Web application (SharePoint Foundation 2010).

·         Verify that the service account permissions for the Web application and the Office Web Apps services are appropriate. The Web application and service applications must have the appropriate permissions to access the content databases and the configuration database. For information about the appropriate service account permissions for the Web application and the Office Web Apps services, see Account permissions and security settings (SharePoint Server 2010).
