On the iSeries, when using Data Manager to update the licence key, the update completes successfully but the licence key file is not updated.
If the target location is set to "/", the licence is installed to the QPGL library.
When you set the target location using "/" you must also click Browse (...) and change the path from "QPGL" to "EPG" or "BW".
After saving the configuration change, run an update to update the licence key correctly.
Note: If you have already run an update after installing the licence, remove any unnecessary entries from the QPGL library.
