Hi Friend,
Here is the simple procedure:
1. In fact it comes with VC bundle itself. When you install VC, on first page itself you will find it.
2. Another way is : Open your browser : Type this address : "https://<Your host IP>" , you will get one page where download link is available for VI client. Download and install.
Note: I did not read your complete post but I assume, you are looking for this. You have other option i.e Web client that too comes with VC bundle.
