The CSDS is licensed on a geographical site basis and access is subject to a Licence Agreement. The software is licensed by calendar year, allowing access from 1st January to 31st December.
Operation is node locked. This means that for each allowed installation of the CSDS, the software can be installed and registered on one machine. However, there is no limit to the number of users that may access the installation.
All components of the CSDS are set to expire a short time after the end of the calendar year. Many of the components require registration for use on each computer. This registration occurs once only when one of these components are used for the first time, and can be done either online or via email.
