When you install an Autodesk Simulation Moldflow product on your computer, the installation will automatically check for the presence of a 3DConnexion device.
If a 3DConnexion device is detected, configuration files will be installed that define the buttons.
If a 3DConnexion device is not detected, the installation will proceed without installing these configuration files.
If you want to install a 3DConnexion device, after having installed the Autodesk Simulation Moldflow product, you will need to re-install the Autodesk Simulation Moldflow product in order to pick up the button configuration files.
