This sometimes happens when some DLL is missing. Make sure that appropriate DLLs are either in system folders or in the same folder where your application is installed. First one is .NET DLL (Innovatrics.IEngine.dll) and the other DLL is IDKit.dll. .NET programmers sometimes forget to install this low-level DLL when deploying their application on another computer. This low-level DLL itself has dependencies on system libraries which can be checked with freeware Dependency Walker tool.
