Another related question...is the QlikView Management API group a new group that would have been added during the On Demand add-on install process or was that part of the NPrinting install process? (I didn't actually do the installs which is why I ask; I'm wondering because I see the info about rebooting the QV and NP servers when the NP service account user is added to this group)
As a last ditch effort we did in fact just restart QV this morning and the button appeared, thanks. But when we select it, it is telling us it cannot find a connection, but we did find that the url had a slash in it and once changed it worked. In addition to that, we also discovered that we think we have to install the On Demand add-on on our extranet server as well because we have 2 ways to get to our Access Point and right now we only see the button via one of the ways and not the other. So I have more research/troubleshooting to do, I guess.
