So, you installed QlikView IIS support on the IISQLIKSERVER? You should have a service there named QlikView Settings Service - can you verify that, and that it's running?
Next, add the IISQLIKSERVER to the service tree in QMC via System > Setup > QlikView WebServers > (add), and use URL http://IISQLIKSERVER:4750/QVWS/Service. This is the service URL that the QVSS on IISQLIKSERVER will host, much like as if you would have installed the QvWebServer on it.
Anyways, the service provides an administrative interface instead of the AccessPointSettings.aspx file that was used for configuring the IIS from QMC/QEMC. The QVSS also handles QVS inter-communication certificates (SSL-encrypted communication between services) when using them and IIS in 11 - that's why it exists.
