DIEF Parameter issue with Newly installed AOS in AX2012R2 CU7 version

Hi Folks,

When the new AOS is installed and configured with the already installed DIEF components, the following error will prompt up while accessing the DMF parameters form in DIEF module.

“System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidOperationException: Unable to find the application configuration file C:\Program Files\MicrosoftDynamicsAX\60\Server\AX2012R2_TEST\Bin\Microsoft.Dynamics.AX.DMF.ServiceProxy.dll.config. Ensure that the assembly containing the specific service client type has an application configuration source file present. Paths below were inspected: C:\Windows\Microsoft.Net\assembly\GAC_MSIL\Microsoft.Dynamics.AX.DMF.ServiceProxy\v4.0_6.2.0.0__31bf3856ad364e35\Microsoft.Dynamics.AX.DMF.ServiceProxy.dll.config
