--- Comment #11 from David dav75uk@yahoo.co.uk --- Admin tool showing fine as of wine 10.0 - Given you can also activate the later Chessbase 17, I'm going to say this can be closed now as it's virtually guaranteed to work with Chessbase 12. I guess if anyone still uses 12, they can reopen if needed.
