Dear Dil
Please download the client from http://www.qlik.com/uk/explore/products/free-download and install it. Assuming that you have SmartView running on a server, when you open the client you will need to choose File>>Open In Server... and then typing in the address of the server and document. For example:
qvp://user@domain/demo.qvw
