Hi ThaSundanceKid,
The error 0x80070666 points to there being another version of the C++ Redistributables already installed. Try uninstalling all versions you currently have and instead installing the latest version from Microsoft:

Hi ThaSundanceKid,
Did you uninstall the other versions of the Redistributables first?
Kind Regards,

Hi ThaSundanceKid,
Also, to address the Unknown Device, you may need to point the hardware to the correct driver. In Device Manager, select the Unknown Device. Right click on it and select update driver. Choose the option to 'Browse my computer for driver software', and then Browse to this location: C:\Program Files (x86)\NaturalPoint\USB Drivers x64\npusbio_x64.
Kind Regards,
