That the services running without an error-message to the windows msc doesn't meant that the services are working properly. Unfortunaltely there aren't easy ways available to check this. This discussion give you more informations about this topic and will be helpful to find a solution for you: check if qlikview server services are alive and able to response.
I think that if the services are down then you couldn't apply a licence - at first the services must run and without a valid licence they would be shown with a yellow icon and the message that they are in an unlicenced state.
One reason why the services aren't run could be that there are errors by the installation - I'm not sure if the qlikview server services could run on a desktop OS like windows 10, normally they need a windows server OS because some of the set configurations and installed/activated tools like NET framework are different. For this take a look within the release notes what the install-requirements are and if they are appropriate then install it new (it's the fastest way of only a few minutes).
Every QlikView service writes messages to its own log file. Situations like this ("disconnected" usually means that a service is unable to talk to the QMS and vice versa) are well documented. Can you check these logs? I suggest you start with the log file of the QlikView Management Service which is located in C:\ProgramData\QlikTech\ManagementService\Log.
For further assistance, please post one or more logs (or the part immediately following a service restart) in this discussion.
