Next start the CodeMeter Web admin program. (Start | All Programs | CodeMeter | CodeMeter Runtime Server). To check this, first, start the CodeMeter Runtime Server with dongle in the USB port. If turning off your anti-virus/Internet Security program does not work, then it's possible (although very rare) that the license is not in the stick. (I'm not certain about this last part, but there should be a way to let Norton Internet Security allow the CM stick to access the port.) (Norton Internet Security seems to block communication to a port that the CM stick uses.) If that fixes the problem, then you need to add the CodeMeter Runtime Server program to the list of programs that the Nortorn Firewall will permit to run. If you have Norton Internet Security, please disable it and see if that fixes the problem.
