Olympus Choir Elements Upgrade activation question

Does the Olympus Choir Elements Upgrade for Dorico Pro/Elements 3 and 3.5 requires the old USB-Licenser for activation or can this also be done via the new Steinberg activation manager with an active Dorico Pro 4 license?

Olympus Choir Elements still requires eLicenser at the moment. We haven’t made any announcements yet about when and how various sound content packs will be migrating to Steinberg Licensing.

Thank you , Daniel. I was asking because I am on vacation and my USB-Key is at home.
