The full Capacity Edition (not the Lite one) includes LEO capability for unlimited drives and should enable this automatically - you do not have to buy a LEO license and in fact in the license installer screen that follwos the one you add licenses into, it wil look like the LEO is not available against capacity if you add a LEO licnese to a server runnign the capacity edition
LEO itself is not an option in the installer, i.e. the screen in te installer that is 2 pages after the one where you add the license files. Library Support is an option that is usually enabled and greyed out, but Library Support is just generic support for a library and has nothing to do with Library Expansion and it is greyed out and enabled as most customers need it.
Where the LEO being part of Capacity should show up is in the Licence Information Screen and in the Adamm.log file.
Read the ADAMM.LOG from the bottom upwards so that you read the last updates and look for a section like this
Shared Storage Authorization: Yes
TSM Authorization: No
SPO Installed and Authorized: No
SPO Limited Installed and Authorized: No
Library Expansion Options: Unlimited
VTL Options: Unlimited
If you still supect LEO is not working then please log a formal support case.
