@PoojaK386 Whenever I see issues launching interrogation, I generally start with Process Explorer to help identify the process(es) that launch and how they are launching. Process Explorer can hep you identify how you need to setup your adapter. FOr example, you might notice that wen you click your shortcut for "hdadmin.exe" a separate process is actually launched while "hdadmin.exe" is closed. This might be why you see an error. You'll need to understand how the process you are looking for starts up in order to interrogate it.
