HALion Sonic SE 3.5.10 - HS SE Artist and TRIP

In HALion Sonic SE 3.5.10 the instruments of HS SE Artist and TRIP are visible but not available (wrong way sign is standing beside)

Novel Piano and LoFi Piano are ok.

Looks like a licensing issue. Most likely reason for the no-entry signs is that you installed something you don’t have license for.

What version of Cubase do you have?
