Once the install is complete there should be a screen that confirms the status of each service. Following that the QMC launches and you should be asked to enter license information.
Are you at that screen ?
A machine that is disconnected from the internet cannot be licensed with a serial/control number only, you need to get the LEF from Qlik to do that.
Please note the licensing is done via the browser and you'll need IE10+ , chrome or firefox to do that as websockets is required (and only exists in those versions).
can you upload a screenshot of where you are ?
The issue has been resolved. The part I forgot to mention was that we had Qlik installed on the "wrong" drive. So, we uninstalled it. But some of the Qlik processes/services continued to run. So I forcefully stopped them, then I re-installed qlik on a separate drive. The re-install didn't go smoothly because of the way we uninstalled the application to begin with. We reverted to an earlier VM snapshot and did a clean install - which worked.
