It is common these days to download the latest update from the manufacturer's website in order to get the latest updates/fixes for the software instead of using the supplied CD. Usually this is the case for Antares products as well, but for AVOX it can cause the software to not be authorized, as the demonstration versions of AVOX available on the web cannot be authorized by the AVOX bundle license that comes in the box. Installing AVOX from the CD provided in the box is best.
