You can choose one-year or three-years subscription.
One-year subscription allows you to use and upgrade nanoCAD during one year. At the end of the year, the license must be renewed, otherwise the program will stop working.
The three-year subscription includes a perpetual license, in addition, for three years you will receive a free upgrade to new versions of the product when they are released. After three years, the perpetual licenses will continue to work, but you will no longer receive product updates.
Also we provide workstation and network licenses.
One workstation license allows you to install and use nanoCAD on one PC, license file is associated with the computer where nanoCAD is installed. Thus, a license for one workstation can be bind to only one computer at a time, and it cannot be used, for example, by installing it on one PC in the office, and on one PC at home.
Network license provides installing nanoCAD to any number of PCs, but no more than number of paid PCs will be able to start nanoCAD at the same time. There should be TCP/IP connection between PCs for using network license.
