I just updated to the latest version (feb 2019) of Qlik Sense on a Windows 2012 r2 server.
And I just installed nPrinting service using the following link; https://help.qlik.com/en-US/nprinting/February2019/Content/NPrinting/DeployingQVNprinting/Installing...
I installed everything and I'm able to acces the :4993 on the server, but logging in with a windows account is not working. Only via email.
After this I need to activate license, on the online page & the offline (https://server:4993/#/admin/license/offline?qlik=xxx&organization=xxx). I get the error: "Wrong LEF"
How can i fix this? Or where can i find more logs?
EDIT: I just found I get this error in my logs: LICENSE ERROR : Invalid product level
