Enable or disable viewers

When Open Client is installed, both the IDM Viewer and Java Viewer are available in the client interface by default. The IDM Viewer must be manually downloaded to each client. If a user selects the IDM Viewer and it is not yet installed, download instructions are displayed.

Note: You must restart the Open Client application for this change to go into effect. Also, client users will not see the change until they start a new browser session.

To enable or disable a viewer

  1. From a text or XML editor, open the SitePreferences.xml file, located in the Preferences subdirectory of your Open Client installation directory.
  2. Locate the parameter value, shown in boldface in the example below, for the viewer you want to enable or disable, and change it to “False” to disable or "True" to enable:

      <subsystem name="Viewing" label="Viewing" 
          description="Viewing" 
          visible="true">
