Nios II license expiration

[Altera_Forum]

We've been using a license for Nios II since 2007. It has always allowed us to generate /s and /f versions of the CPU in SOPC Builder including 12.0sp2. We want to move to QSys, but we are seemingly unable to generate a licensed CPU in QSys with this license. 

 Does the Nios II license expire ? Or is there a Nios II version for QSys that needs to be licensed separately ?

With QSYS, Nios licensing seems to be a little different :  

Nios II/e is free Nios II/s and /f are licensed.  While with SOPCBuilder, all Nios II (/e /s and /f) are to be licensed (by fee or by buying an Altera NIOS kit)  So, not 100% sure,  yes and yes.
