Techstream install on 64 bit O.S. Windows 7/8/10

Toyota Techstream software is verified to work no issues on 64 bit operation systems incl. Windows 7, Windows 8, Windows 10.

FYI, Techstream Windows 64 bit is tested by users, not pros working for

Here you go.

Techstream Windows 7 64 bit:

Quick note on techstream 10.x with windows 7 or greater x64 with the 1.4.1 (and possibly the 2.0.1) Mini VCI cable. I was having absolute fits trying to get the driver recognized. Turns out the cable was being recognized as a Broadcom Bluetooth 3.0 Chip. If you select that device, Select Update driver, Select Let me Pick From a list of device drivers on my computer (letting windows scan a specific location doesnt work), then click have disk and browse to the location of your MCVI drivers (Should be C:\Program Files (x86)\XHorse Electronics\MVCI Driver for TOYOTA TIS\) and go to the ftdibus directory and select the ftdibus.inf file. This will get the correct drivers in place for the bus. The COM drivers will install automatically after you get the bus driver in place.

Hopefully the search engines pick this up and it is helpful for someone else.

Techstream Window 8 64 bit:

Got my Techstream (10.30.029) cable and software working on Windows8 64-bit laptop. Here’s what I did.

  1. I ordered this cable/software from Amazon. Was $15 with slow boat shipping, took 2.5 weeks to get.
  2. Load this page since I used this for most of my steps,
  3. First thing you need to do is install the driver for the USB/OBDII cable. Follow the steps outlined in”Installing MVCI Driver for TOYOTA” of the ft86club post. I used the “Mini VCI Driver for TOYOTA.msi” in the 10.30.029 folder that came on the CD from Amazon
  4. After drivers are properly installed and you verify you can see the device connected on the XHorse Firmware Update Tool, you’re GTG
  5. Next up is the Techstream software, from the included CD I ran the “Toyota Techstream 10.30.029.exe”. After installation I went into the C:\Program Files (x86)\Toyota Diagnostics\Techstream\bin folder and replaced the “MainMenu.exe” file with the one found on the CD.
  6. You should be able to load up the Techstream link that was installed on your desktop. When it asks to register with a new key, use the key found in the “serie.txt” on the CD.
  7. Next you’ll need to update your registry, on the ft86club post there’s a Dropbox link and with a “mvci-x64.reg” file, download this and run it.
  8. Open up Techstream, go to Setup menu, VIM Select, and choose the XHorse – MVCI. This will have Techstream use the XHorse – MVCI cable.
  9. If you try to Connect to Vehicle you’ll get a message that forces you to update the software. To get around this disable your internet connection (turn off wifi and/or unplug your ethernet cable). Now you can start and use Techstream without the force update check.
  10. When you connect there’s a counter in Techstream that only allows 30 connections to your car without an internet connection. To get around this go to the C:\Program Files (x86)\Toyota Diagnostics\Techstream\Env folder and open the “IT3UserCustom.ini” file. Towards the bottom there’s a “ConnectionCount” variable, just update this to 1 when you get close to 30 connections.

This worked for me… hopefully this will save everyone some time/hassle. I would be careful of what you try to update in Techstream. I just updated the unlock so a single press will unlock all the doors. I also viewed some data on the TPMS stuff.

Techstream Windows 10 64 bit:

This link describes the installation process, possibly with link to the software.

I think the first requirement is that your mini VCI cable hardware is capable of 32 and 64 bit, I think some of the earlier cables may be 32-bit (XP) only. If capable of 64-bit, then they give you a small CD with some special files “XHorse” and it takes a little bravery to mess with your Registry etc.

Btw, Many people will not be able to follow the instructions to install the necessary cominents. No judgement here, it is just reality.

Which is why I up telling people to stick with using an XP laptop instead.

That would be great if you have an XP laptop (or desktop) available…it is definitely a much easier install. But going forward I presume that’ll be harder to find. I thought the Win10 instructions were a little confusing but I worked thru it.
