What kind of setup project have you created? Is it selfregistering COM component? Are you sure the registry of target machine has values for your COM classes and interfaces?

Can u please let me know how to check that?

To check that your COM registered in the right way you can use OleView.exe utility from your Visual Studio tools, or to search registry in following keys:
HKEY_CLASSES_ROOT
HKEY_LOCAL_MACHINE\SOFTWARE\Classes
If there are no any signs of your COM class, then you need to extract your COM interfaces data from typelibrary and incapsulate it into your setup program.

If your COM class registered successfully in target system, then I suggest you to switch configuration from "Any CPU" to "x86" in project's properties, "Build" section.
