Interop.zkemkeeper how to connect c#

I have a bio metric devices to connect C# project.


I added to my project and trying to connect the device.

When I create the object “CZKEMClass” this class its getting error

An unhandled exception of type ‘System.Runtime.InteropServices.COMException’ occurred in WindowsFormsApplication1.exe

Additional information: Retrieving the COM class factory for component with CLSID {00853A19-BD51-419B-9269-2DABE57EB61F} failed due to the following error: 80040154.

My code:

public zkemkeeper.CZKEMClass axCZKEM1;
private bool bIsConnected = false;
private int iMachineNumber = 1;

public Form1()
    axCZKEM1 = new zkemkeeper.CZKEMClass();

    Is this library 64-bit? Try to open settings of your project and set build target Any CPU or x86.
