How to Install Toyota Techstream on Windows 8 64-bit laptop

Got my MINI VCI Toyota TIS Techstream (10.30.029) cable and software working on Windows 8 64-bit laptop. Here’s what I did.

  1. I ordered this cable/software from Was $16.99 with slow boat shipping, took 1.5 weeks to get.
  2. Load this page since I used this for most of my steps, Techstream TIS VCI Installation Guide (64-bit OS) Including All Software Needed! – Scion FR-S Forum | Subaru BRZ Forum | Toyota 86 GT 86 Forum | AS1 Forum – FT86CLUB
  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.
  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 Toyota 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.
