Default System.Runtime.InteropServices.COMException: Catas


I am using an OCX control in ASP.Net application using C#. Here is the code:

DWGINFOLib.DWGinfo cadviewer = new DWGINFOLib.DWGinfo();
cadviewer.unlockKey = "XXXXXXX";

Whenever I tried to access its property or method, it says:

"System.Runtime.InteropServices.COMException: Catastrophic failure"

Does someone know its solution?
