Hello OptionD,

have you had an older version of the driver installed previously? If yes, do you remember which version? Do you still have the installer for this driver? If yes, please proceed as follows:

1. Uninstall any 3Dconnexion driver (if you have something installed).
2. Reboot the machine.
3. Install the older version of the driver.
4. Reboot the machine.
5. Uninstall the older driver.
6. Reboot the machine.
7. Install the latest version of the 3Dconnexion driver.

Let me know if this works. In case you do not have the older version of the driver let me know.
If you don't remember which driver version you had installed previously I recommend to contact our Technical Support Team. Provide them with logfiles from the installation. See here how to create the log files.
