Just received Techstream cable last night and installed the software on my 64 bit computer. Installation was not plug and play, but it is quite doable.
3. Open the Device Manager and locate two failing devices in the list. Both will appear with yellow icon (usually under ”Other”), indicating that Windows failed to install drivers for them. Now, right click each failing device, select Install Driver, then ”Browse my Computer” and locate to “C:\Program Files (x86)\XHorse Electronics\MVCI Driver for TOYOTA TIS” (enable the ”include subfolders” flag). Click ”Next” and wait until drivers are installed.
You should now see two new devices: ”Universal Serial Bus Controllers\USB Serial Converte” and ”Ports (COM & LPT)\USB Serial Port (COMx)”.
4. Run the FirmwareUpdateTool.exe from the “C:\Program Files (x86)\XHorse Electronics\MVCI Driver for TOYOTA TIS”. Click ”Device Info”, You should see the ”Device connected” screen.
* Attention: It’s C:\Program Files (x86) not C:\Program Files\ , BIG DIFFERENCE !!!
11. Connect Mini VCI cable to your car‘s OBDII interface, turn ignition on, then click ”Connect to Vehicle” in Techstream. Wait. Then wait again. If everything works, you will be prompted to confirm car year/model after which you’ll get to the diagnostic interface.
