This is a cutomer feedback on Xhorse MVCI interface operating system requirement.

Windows XP, 32bit – You cannot use windows 7/8 or any other operating system to run Techstream. MUST be 32bit, cannot use 64 bit.

If you have Windows 7, Mac, ETC, you will need to run a virtual machine. This is basically a “window” that runs windows XP inside of it.

For windows users you can use Windows Virtual PC.
*NOTE – if you have Windows 7 Home premium edition, you cannot use this unless you follow a few steps and watch a YouTube video on how to get it to work. The audio is real low and the kid is like 8 but the directions are spot on, I followed them and it works.
Original XHORSE MVCI 3 IN 1 is a high performance factory diagnostics and reprogramming interface for TOYOTA TIS.
MVCI is compatible with Toyota, Lexus, and Scion vehicles, over the J1962 DLC3 connector.
