Not recognized windows 7 64 bit. Inconue error of Windows 7. No software. On the packaging Windows XP / Vista / 7/8. No indication 32 or 64 bit? Too bad, good product presentation. As I still have 2 pc with XP I will equip motherboards to upgrade to Windows 7 (I hesitate with Windows 8) I will try with a 32-bit version Hoping it will work. I saw one comment that it does not work in 64-bit. All comments indicating proper operation do not indicate in any software. A significant lack of precision.
