Also the issue is happening only for non admin users and we need to provide our app to non admin users of Windows 7 64 bit OS, where the issue is happening.

Such COM error message indicates that an OCX component that you are trying to create is not registered in a system, or COM cannot create it in the context of your application. 

This is possible, for example, when your Java application is launched with a 64-bit JVM, and a required OCX component is a 32-bit COM library. If so, the simple solution is to start your application with a 32-bit JVM.

By the way, this is JNIWrapper support forum, and actually it's nothing to do with COM.
