Hi @kyru,
you need a VST Viewer license in your Steinberg Activation Manager (SAM). Please visit the VST Live 1.1 website and watch out for the “GET VST VIEWER” button. Press that one and be sure to be logged in with your SteinberID account. The same which contains the VST Live Trial license. After you have visited the Viewer site, a license for the Viewer will be added to your SAM application.
Does it work?
Michael.
