I realize that my question is partly related to what has been discussed in recent posts in topic I have already HSO licence, how to proceed with new Dorico installation?, but I would like to be sure.
I do not have anything beyond Dorico on my system and am not using the USB licenser.
I have upgraded from 2.2 to 3.1 without a hitch, with playback sounding OK for all the files I tried, but am wondering whether I must also run the setup.exe file found in the huge HALion_Sonic_SE_and_Content_for_Dorico_Pro_3.3.1_Installer_win.zip. Will its contents be installed automatically in C:\Program Files\Steinberg\HALion Sonic SE, updating and adding as needed, or will it be installed in a new directory of its own, specific to version 3. Thanks in advance for reassuring me.
