Halion Sonic SE2 Content with Cubase 7.5

Can anyone help?

Does the content of Halion Sonic SE2 install automatically when C7.5 is installed?

Or do I have to initiate this separately (from within the HALion_Sonic_SE_2_Installer_win.zip download).

By the way, I have full versions of Halion Sonic and Halion5, so maybe there’s redundancy. All the same, I’d like any new sound content that’s SE2 specific.
