We provide workstation and network licenses.
One workstation license allows you to install and use nanoCAD on one PC, a license file is associated with a hard disk serial number.
Network license is "floating" and provides installing nanoCAD to any number of PCs, but no more than a number of paid license seats will be able to start nanoCAD at the same time. There should be a TCP/IP connection between PCs for using network licenses.
