Following the documentation for multi-instance support the application, running as a web service under IIS7 on Windows Server 2008 R2, is failing to access the object. For a single instance I use CreateObject("InDesignServer.Application") but as document for multiple instances I use GetObject(“myIDS1”) (where I have an instance of InDesign Server CC running with parameter “indesignserver -configuration myIDS1”. I have tried running the instance both from command line, elevated command line, and from the InDesignServerService). It is acting as though it does not recognise the instance name, but then I don't really understand how it would. Any ideas appreciated.
