This functionality was removed in Update 33. Starting with Update 33, a new view control is used for View and Markup of certain file formats, mostly non-Hexagon.
To access a Brava! Enterprise Server from one or more application servers, the IP addresses of the servers must match those specified by the legal.ip.to.get.sessionid property. This property is in the server.properties file on the Brava! Enterprise Server. This file is delivered to [installation location]\SmartPlant\Markup\Brava! Enterprise\Brava! Server by default. For example, if legal.ip.to.get.sessionid is set to a wildcard IPv4 address such as 192.*, requests will only be accepted from servers with matching 192.* addresses. The default is set to the localhost IP address.

For a list of acceptable legal.ip.to.get.sessionid property values, see the OpenText® Brava!® Enterprise Administration Guide delivered to [installation location]\SmartPlant\Markup\Brava! Enterprise.
