I'm using Windows 8.1 and I have many problems with 3D Vision. People tell me 3D Vision don't work fine in Windows 8.1 but it works in Windows 8. Problem is I don't have Windows 8. I think the ISO I need is: ja_windows_8_pro_vl_x64_dvd_917950.iso (listed as "Windows 8 Pro VL (x64) - DVD (Japanese)" in MSDN) If anyone has it and can share, I'd appreciate it.
