I’ve have installed Cubase LE AI Elements 7 on Windows 8 and everything is fine on Cubase except that none of the sounds are in The Halcion Synth Program. I found all of the sounds individually separate in the Programs file and don’t know what to do next… 
Hello,
Is Halion Sonic SE showing as a plugin to load? are you getting any specific content error messages?
Yes, it is a plugin? When I load it from the instruments (coming from VST), it pops up as a separate window. When I load up a new project it says “some audio files are missing, please check installation” directing to Halcion Synth SE
