but i cant not create object of it giving above damn error.pls help.

That interop.X.dll is actually a wrapper around some other, unmanaged DLL that's called something like fixengine_com.dll - you need to deploy the latter on the machine where your code is running - specifically you need to copy that DLL and all its dependencies and run regsvr32 to register it with COM. That unmanaged DLL contains the COM server - actual code that will serve your requests and the interop.X.dll is only a wrapper to route calls from your managed code into that unmanaged COM server.
