Welcome to QlikView.
Yes, there is client server installtion architecture. You have to buy a server licence. Install the sever (it's a different software than the client verision). Then install the client software in the developers' local system. Now there is a process called 'licence lease' which allows local users to lease license from the server, then the developers would start the development. (Apart from this, you can always opt to develop using personal edition of QV which does not require any licence and which has limitation of using only self developed applications.) For more details and understanding, please contact a local QV partner.
Hope this helps.
Simply free download the Client version from http://www.qlik.com/ as per your Machine 64/32 BIT you can install and start the development as trail version with some limitations which i thing for a start you can ignore.
