The 3dxWare package installs an emulator which basically lets the 3dconnexion device pretend that it is a game controller. However, this wil cause problems in the Machines Simulator camera movements.
So, you need to disable the KMJ emulator using these steps:
1. Go to Device Manager
2. Switch to View – Devices by Connection
3. Under 3Dconnexion KMJ Emulator, look for HID-compliant game controller
4. Right-click and disable it
It will no longer show up under Game Controllers in Windows and Machines Simulator will work correctly.
