The manual and driver for supported OS versions are here: http://www.dxgusa.com/downloads
. The manuals for all of their cameras are listed first and then the drivers. They are listed in order so the DXG-572V driver is in the third line, third from the right of the driver section.
The driver may not have been updated from the original which for Windows XP/ME/2000/98SE. In Windows Vista 32-bit the driver may work or the correct driver may be in the OS. For Windows 7 32-bit, use the driver built into the OS. (Microsoft's compatibility center provided the information.)
With the 64-bit versions of these newer versions of Windows, the compatibility is unknown. However, the driver from the DXG site will probably not work without the compatibility mode, if it works at all. For compatibility mode, right click on the exe file and choose Properties, select the Compatibility tab and set it to run as Compatible with an older version of Windows. Then right click and Run as Administrator. Otherwise, keep it on a computer with the older OS, use a dual boot with the older OS or a virtual computer with an older version of Windows. With Win7 Pro or Ultimate, you can use the XP mode for a free virtual computer. (Download and install Microsoft's Virtual PC and then XP mode; install the camera to the virtual computer.) All other methods will need a licensed version of an older version of Windows. The only issue with the virtual computer is that files can't be shared between the two computers directly. Put them on external or optical media to share them with the real computer.
I hope this helps.
