Toyota Mini VCI on 64 bit Windows

Mini VCI

I purchased a Mini VCI cable to perform diagnostics on a Toyota from an online site and it arrived with a cd containing drivers, the Techstream software, and some PDF documents with instructions.

The main files of interest on the cd were ‘MVCI Driver for TOYOTA’ and ‘Toyota Techstream 8.00.034’.  Reading the instructions it required me to install the MVCI driver followed by the Techstream software.

The MVCI driver repeatedly failed to install so after a quick search it appeared that other people also had this issue when using 64 bit versions of Windows 7, I was running 64 bit Windows 8.

The solution was very simple are required manually extracting the MVCI driver, I used 7 zip which worked very well but the are many other applications that will extract this installer.  The steps are as follows:

  1. Create the folder C:\Program Files (x86)\XHorse Electronics\MVCI Driver for Toyota TIS
  2. Open the file MVCI Driver for TOYOTA.msi with 7zip and extract to the folder you created.
  3. Browse to the folder with Windows Explorer.
  4. Right click on the file ftdiport.inf and select install.
  5. Right click on the file ftdibus.inf and select install.

Connect the Mini VCI cable and run the application FirmwareUpdateTool and click the Device Info button.  If your device is showing as connected then it is ready to be used with Techstream.

    Hi Paul. Thank you so much. After reading tons of other information, these directions were the clearest., I was able to connect My MVCI to Techstream. Do you have any links to do the same for HDS and others. No matter what I try, I can’t seem to get HDS to see My mini MVCI. I am running windows 7 64 bit. Thanks in advance.

    My driver installation keeps saying it has ended prematurely. I have the ftdiport and ftdibus installed and it will not allow the driver to finish installing. Any ideas?

    The Techstream software I bought on line from China loaded onto my W7 Home Premium 64bit. However when I opened and clicked on ‘connect to vehicle’ I got a window asking for a license number. Since none came with the disc or material, I am stopped for the moment. Has anyone had the same experience or found a way around it or a way to get a license code ? Thanks for any insights.
