Troubleshooting
Problem
User launches the Controller client via a web link. * For example (if using Controller 10.1) user launches shortcut to http://controllersvr/ibmcognos/controllerbin/ccr.exe * Alternatively selects the Controller link on the "Cognos Connection" website's welcome page. However, the Controller client does not start. Instead, user receives an error message. NOTE: The Controller client works OK if the user has the 'local' (non-web) client installed. * In other words, it works OK if they have the CCRLocalClient.MSI version of the client installed.
Symptom
Screen:
- System.NullReferenceException: Object reference not set to an instance of an object.
at Cognos.Controller.AppContext.InitConfig()
There are no errors recorded in the Event Viewer.
