Here is possible issue:
1. Check QlikView services and make sure all start with domain account (service Log On with domain/username).
2. Make sure you try to apply license on different LAN. Ex. You have apply license in Server1 in LAN1, then you try to install another Server2 in same LAN1. Here second server will fail to apply license.
3. LEF contents maybe generate wrongly. You may generate new LEF via http://lef1.qliktech.com/manuallef/
4. Last one is contact your partner manager or email@example.com
right Click on each qlikview services ------> Properties ----- Logon
uncheck local system account and check this account
type username and password which you have currently logged in click apply and restart the service.
do the same for all the 5 services
Pls Note : The account should be a member of Administrators and Qlikview Administrators Group to check list of Administrators group
Run------>compmgmt.msc----> local Users and Groups-----> Groups
Hope it helps
