I would like to know too..
edit: Maybe I'm wrong but this "QlikView Connector" is really an ODBC connector from other vendor. I manage to get the manual and it seems that the Server is for client/server environments and the Workstation for use in PC's like you would use it for Excel or Access. IT says nothing of the "desktop" however..
Here's the answer:
There are 2 types of connectors and 3 installation packages that can be downloaded:
1 - The Client-Server edition is for use with QlikView Publisher. It has 2 installation packages.
2 - The Workstation edition is for use with QlikView Desktop
The packages are called Qvc_SRV_sfdc.zip & Qvc_CLI_sfdc.zip for Client-Server and Qvc_WS_sfdc.zip for Workstation.
