Hi Kiran,
As per my understanding, you are trying to open and spy an MS Access database file. Here is the way , we can achieve it.
Set Application Modeller as Windows Application Type and pass the .accdb file in command line parameters and then launch it.
But the only mode you can spy a .accdb is "AA".
Reply me if you have any other issue, I can help you as I am currently working on .accdb file in my project.
