Hi François, thanks by your reply.
When we try to see the server's folders (Management Service > Qlikview Servers > QVS@XXXX) appears this error:
This is a new server installation and our QV Commercial only sells us a Qlikview Server license, we have not Qlikview Publisher valid key... maybe the problem is here? to manage our docments we need to have the Publisher license too?
To manage your documents, you haven't need to have Publisher licence too...
I copy the post of Jay Jakosky :
I had this problem today. To fix it...
Delete the Publisher LEF from C:\ProgramData\QlikTech\ManagementService\Publisher LEF
Remove reginfo.ini from C:\ProgramData\QlikTech\ManagementService
The presence of reginfo.ini was causing the management service to contact the license server and recreate the LEF automatically!
Gives us news of your issue,
Did you change QVS login credentials for QMS (see QMC->System->Setup->QlikView Server->Login)?
Has your QlikView Server license expired?
