5 New Member
Hi,
i have an windows application which uses an user built dll which uses COM dll. I have kept that dll in the bin and referenced in the project. it built sucessfully . I have created a setup.exe of this application and have installed in my machine . Now when i tried running the exe i got the following exception:
"System.Runtime .InteropService s.COM Exception(0x800 40154):COM object with CLSID{EAA4E7EC-19EC-4576-ABFB-128BC024B429} is either not valid or not registered"
Can anyone help me?

Thanks.

Hi BLavanya,

Try going to Start > Run > Type "regsvr32 yourcomobject.d ll" (replace yourcomobject.d ll with the full path and filename of the DLL you are referencing in your project). This should then register the COM class in the Windows Registry and then can be referenced from your app.

Hope it helps.

I am trying to work on an application that uses a dll as a COM object. I am coming in late to this project to administer/update the application. I notice in the References that a particular DLL is referenced as "Interop.DLLName" and I have the original DLL file as just DLLName with no Interop. My first question is why is the word "Interop" on the beginning of the DLL name and how do you get it to that state?
