How many developers can you be on a qlikviewserver? I don't see any information about a special license or something (other than qlikview server license). Is it enough if you have a named user cal and access to the qlikview server?
All you should have to do is Lease a license from the QVS. If you install Personal Edition, use the start page to connect to the QVS and lease a license. I believe that you need a User CAL, which you have.
