Missing Halion Symphonic Orchestra

Good afternoon everyone,
I have a problem that should be common to many of you.
I changed (by cloning) the disk C: (where windows resides), everything seemed to be fine until I verified that, despite appearing and playing well in the Dorico projects, and within Halion 6; in CUBASE 12 PRO it doesn’t even appear on the right in the “instruments” and the pre-listening of “Loops and Samples” doesn’t play anything directly, I have to transport it into a CUBASE project creating a track just to pre-listen.
If you can help me to improve this situation, thank you in advance.
Best regards,
