When I start the program, I get a message that “The key is not bound to this machine” and the program stops.
The legacy PLAXIS 2D and PLAXIS 3D programs have two types of licences: the flexible and the standalone licence. The flexible licence is a concurrent user network licence, where the number of licences is the number of users who can access the program at the same time. If you only need to use the program on one computer however you can also go for our slightly cheaper option of the standalone licence. This licence can only be installed and used by one user on one computer.
