If you have installed Cut Planner on multiple workstations, we advise you to update and install the latest version of the software on all workstations. This is the only way we can guarantee full compatibility between applications and the lack of downtime in the product development process. The dongle is a hardware device (current electronic device) that gives the user the right to use the software (applications) in full license mode, based on paid licenses, and therefore we recommend that the dongle be used on a the only workstation.
