HalionSonic3 library

when I have installed Dorico in my computer it was already there HalionSonic3 and Halion 6 with all library, but Dorico loading the SE version and the big library of halionsonyc is not visible. How can I include library in HalionSonic Se?

This problem is only in Dorico; fortunally in Cubase 9.5 it’s all OK!

Thank you very much!

If you stop Dorico, then delete the folder VSTAudioEngine2 (OSX: /Users//Library/Preferences/VSTAudioEngine2 or Win: C:\Users<yourname>\AppData\Roaming\Steinberg\VSTAudioEngine2_64 ) that will force a rescan for all libraries during next Dorico start. Does that make any difference?

Thank you, I tray It today.
My O.S. is windows7 64 bit.
