About the eLicenser issue: I saw during the installation of the update installer on my 10.0.30 system / Windows 10 Pro / 1903 (without the latest feature KB) that eLicenser software was installed/updated, which surprised me. As usually, I started the eLicencer control center after the update and it threw a couple of errors about too old / outdated files and components. Then I downloaded the latest eLicenser installer from Steinberg and installed it and after that the control center opened with no errors. Also CB 10.0.40 opened without any problems.
Anyways, not very professional and a bit concerning. Should not happen…
