After three weeks and no support, I have tried everything written before, even the elc-installation-helper program without an acceptable result.
At least I have a stable, empty eLicenser Control Centre, but no virtual container (harddisk icon), no logical explanation, and no other suggestion than contact the vendor technical support that hides behind an unsupportive website. Support at Steinberg sucks and no wonder other companies get better acceptance from their users. Understanding that Steinberg has got almost 6 735 new support tickets since three weeks ago, the picture before us users is very dark. Learn another DAW/Sequencer and use more reliable software.
