Ziggi-HD does not require a driver to be installed because it uses the UVC driver that is pre-installed in all Windows OS later than Windows XP SP2. The Presenter software package only includes the visual interface and control, not the hardware driver.
If you are using Windows XP, please upgrade it to the latest version, SP3. If the computer still asks for the driver, and you cannot see the live image of Ziggi-HD in Presenter or Skype, then it's probably a case of hardware failure.
