On Windows 10, there are problems with the drivers which cause additional issues within the communication of Easyport and MecLab.
Therefore we would ask you to install both the setup_usb_2.15.zip (https://ftp.festo.com/Public/DIDACTIC/usb_driver/) and Fluidsim MecLab 6 (https://ip.festo-didactic.com/InfoPortal/MecLab/Software/EN/) .
