Halion Error Message on Cubase 12 after Cubase 13 Install

After installing Cubase 13 I now get an error message when I load Cubase 12 warning of no licence found for for Halion Sonic SE Content.
I have licences for both Cubase 13 and Halion 7 on my activation centre which ought cover all Halion versions as far as I was aware so why this error message and how do I clear the issue. Library App shows no warnings either and it’s not possible to see what specific Halion SE content it can refer to. I attach a screen shot.

Any advices appreciated


Hi. I’m havig the same problem. No clue.

No idea what’s changed but issue no longer there for me on C12 boot.
