If you have installed second instance of AX 2012. Following are the problems. 1- The specified client configuration does not contain valid WCF settings. 2- As an administrator, Workflow is working fine for editing or else. But for the other users it show error. ": The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state." Suggestions looks like WCF setting issue... Create a new client config and create a new wcf connection from client configuration. also make sure full CIL is generated successfully since service classes are used in 2012 workflow. 1) make sure the server name is used not the ip and server name is reachable (pingable) from client for 2) Make sure u installed .Net Framework and all its updates / hot fixes are installed.. sometimes .net Fx 4 and client profile 4 has issue
