No additional software is required to run BRIO.  We do offer optional applications that allow you to configure settings to your liking or provide additional functionality, such as our Camera Settings Application.  Again, this is optional software for your convenience.
 
One exception is if you are running BRIO with Windows 7.  Because Windows 7 does not support USB 3.0, you will need a driver.   Windows Update should provide this driver, just make sure Windows Update is enabled on the computer.
