I just purchased my G Tablet so I'm very new with this. I tried connecting my tablet to a Windows Vista 64 bit OS (via the mini USB cable) and I kept getting an error saying my computer could not locate a NVIDIA Harmony driver. I contacted the Viewsonic support line and they essentially said that 64 bit OS is not supported. I then tried connecting to a 32 bit XP OS computer and I essentially get the same message unable to locate the driver. All my online searches for NVIDIA Harmony drivers lead me to developer forums where they talk about using SDK's to develop drivers. Is they anywhere I can go to just download a driver for Vista or XP
