Assuming this isn't due the OS (as Bill says Windows 8 is not supported) then....
I would be question where your Document Root is. Is it local to the machine or on a Share somewhere? Note that for the document folders we *only* support either local storage or a "true" Windows share hosted on another Windows server.
I have version 11.20.12904.0 and the same problem.
I think I've fixed in this way:
- Access QMC
- Click on System -> Licenses - Qlik View Server License
- Then click on "Update License From Server"
- Then Apply
Now on "Status" -> "Services" you should see everything is ok and running.
It's worked for me: hope the same for you.
