No keyboard visible

I haave just transferred my Halion 6, Cubase, and Wavelab files to a new machine, using the
various .EXE files to update to the current versions.
All work well, with one exception of Halion 6. The keyboard in stand-alone mode has dissappeared.
It (the keyboard) is also not visible as a VST instrument in Cubase, although it works with no issues
as a VST instrument.
Is there a switch or something that I’ve missd?
