No VST instruments when I open Hallion SE3

Downloaded Hallion Sonic SE 3 but no instruments show up when I open it in Cubase 8.5 I re-installed HSSE3 and followed the instructions as per When I opened the installed HSSE 3version in the Steinberg Download Assistant, and clicked on Hallion_Sonic.SE 3_Installer_win, installation begins, almost finishes, and then I get a Windows error message “Setup has stopped working” . This has happened repeatedly.
Please help!! Thanx! Bruce
