Hi
Hope everyone is staying safe and making great music.
I currently have Cubase Ai 10.5 but in my version of Halion SE 3 there is no Flux instrument. I have read that you have to have version 9.5 installed. I went from version 8 straight to 10 then 10.5 . is there a way to install this without installing 9.5? I currently have 10 and 10.5 on my drive and don’t want to delete 10 in case it is being used by 10.5. Thanks in advance.

I’ve kinda answered my own question when i found this on the steinberg website. Only problem is I’ve tried it and still not appeared!
Windows
• Close all programs.
• Open the “Run” command prompt by pressing the Windows logo key + R simultaneously.
• In the command line of the ‘Run’ window, enter one of the following path shortcuts::
user specific installation (standard): %appdata%
installation “for all users”: %programdata%
Simply use %appdata% if you are in doubt.
• A new Windows Explorer Window opens.
• Locate the folder ‘Steinberg’ and open the folder ‘HALion Sonic SE_64’.
If you can’t find the folder or files, please try again using the other path shortcut.
• Delete these files (to keep a backup, simply copy them to the Desktop before):
ContentManager.xml
mediabay3.db
scannedFolders3.bin
Next time you start Cubase, the deleted files will be rebuilt. Therefore, startup might take a bit longer. As soon as Cubase is ready, FLUX should be at service in HALion Sonic SE.
