Run the eLicenser and register IconicA using the activation code.
All Steinberg software looks to see if it is licensed whenever it starts up. Anyone can install Steinberg software just fine. But you can only run it if the eLicenser says you can.
And yeah the download time on Iconica is brutal. I am planning on buying it, but I wonder how much of that is influenced by not wanting to waste all the effort it took to download.
