I upgraded to Backup Exec 2016 FP1 and installed new licenses for the Library Expansion Option as I have a Tape LIbrary with 2 drives. I started to get the error message Library Expansion Option Violation. The server is licensed to support 1 tape drive in robotic libraries. The license is installed and appears as installed if I run the Install Options and Licenses on this Backup Exec Server. I have remoeved and reinstalled the license and I have run tapeinst.exe. There is only 1 library listed under the Storage tab and there are only 2 tape drives listed under the libary.
What does it state in the License information / License summary screen inside the BE console? (as far as I can tell you are looking in the license installer options which are designed to handle push installs to remote servers etc and therefore does not mean you have actually installed it correctly on that specific server
Also what core product license are you using i.e. (Standard BE server, Capacity, Capacity Lite, R-Ray etc) as LEO is not compatible with at least one of these - Capacity Lite does not allow LEO use
