I found this last week, and it worked wonderfully on my Asus Windows 8.1 Intel i3 notebook:

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

The thread includes a dropbox link where you can download "all" of the needed files, but really all you need from there is the MVCI driver and the .reg registry hack file.

Get the latest Techstream from:
How to install Toyota TIS Tehcstream V10.00.028 software most detail « UOBD2 Official Blog

There are a number of steps to getting the driver installed manually, be sure to follow ALL of them before plugging the cable in.
On my 8.1 installation, when I plugged in the cable, Windows automatically looked for and installed the driver, so if you haven't followed the instructions to that point, it will load the 32 bit driver.

After installing the driver, you need to run the registry hack. Mine downloaded as mvci-x64.reg.txt (might be a Dropbox restriction), simply rename to mvci-x64.reg
After renaming the registry hack file you then need to run the file, which will merge the contents with the registry (will probably get a Windows modification confirmation)

Once the driver was loaded and I verified with the firmware update utility that it was communicating (don't try to update the firmware), I was ready to install and run Techstream.

Again, follow the directions on installation.
One .ini file needs to be edited to "activate" the program.

Upon loading, you'll need to select "Europe" and then your preferred language. The key thing is that only the "Europe" option works.
For the user and all other blank mandatory fields, I just typed in "111" and left the default "Albania"

Next, select VIM type xHorse
Now, you'll want to set your preferences for units. It defaults to metric, and it also defaults to absolute for the TPMS so at first you'll be scratching your head at the 46psi tire pressure... set that one to "gauge"

Good luck!
There is no need to launch anything in XP compatibility or anything (at least not on my Windows 8.1 system)


Edit 4-15-2016: Bought a '16 Corolla in February and it worked just fine. The notebook was upgraded to Windows 10 last summer and I never got around to testing Techstream.

I am trying this on Windows 10 Pro 64-bit.

However, when I am running command "msiexec /a "C:\temp\Techstream\MVCI Driver for TOYOTA.msi" /qb TARGETDIR=c:\temp\mvci", AVG software is finding viruses. Is that OK or is the downloaded file infected?

I've installed several versions of Techstream from 8.0XX to 10.030 on my old XP laptop, Avira AV kills the Trojan every time and the driver doesn't work, the only way I could get it to work was turn off Avira and let it install the Trojan and driver. So my old XP laptop is dedicated as a Techstream tool only, wifi turned off.

When you run the cable check utility, do you get a green bar on K-Line and L-Line or are they both red?

Been a while since I've run mine but I seem to recall they were red as well.
Caused concern but most everything worked. There were a couple of modules that would not communicate.

I'm not detecting any trojan/virus with mine.

From my research I suspect many who don't detect the Trojan infection aren't using a good AV or don't keep it updated, I ordered three different MVCI units from Amazon and downloaded several Techstreams from sources recommended here and other Toyota forums, they all had the Trojan infection when installing the driver. Whether or not the infection really is an actual Trojan or is just how the file is recognized by AV programs, but I'm not willing to use it on a machine that I have personal information on, after all, the Techstream software we're talking about came from China and we all know what they've been up to for the last few years. I run Avira Free on the laptop. https://www.avira.com/en/avira-free-antivirus

I think it's a false-positive due to the way the installer is run.
I've installed this on 4 different notebooks running Symantec, Kapersky, and AVG all coupled with Spybot.

I just installed V10.00.028 on a Win 10 x64 laptop, install went fine, Win10 loaded its own driver for the cable, but I haven't connected to the vehicle yet to see if it actually functions.

Francesco, I am lost. My goal is to program a valet key for the same vehicle you have. I have the latest TSI software and have tried to follow the detailed installation post for Windows 8.1. I believe the driver is the problem. I have the 64 bit on the laptop but I believe the 32 is installed and can't get it to change. Any tips you can offer? Thanks.

CB9, I had a hard time following this. I believe my Connection Error is due to a driver problem. My goal is to have a valet key. I have a Windows 8 PC and a 2015 Rav4. I got the software to load and come up but cant get the connection. Any tips would be greatly appreciated. Thanks.

Purchased the MVCI interface cable and software on a mini-DVD from a Amazon partner vendor and tried to install it yesterday. The mini-DVD was cracked and the mylar was coming up. Was able to get a few small files off it, but not the 137Mb techstream file. Thankfully, that is available for download from just abut everybody.

No luck getting it to run last night. First tried on a Mac running virtualbox, then on an old netbook I had lying around that I kept a copy of Win7 in a partition after I installed Linux on it. Checked all my old netbooks and finally found one that still had XP on it.

Installed it this morning on that XP netbook and was able to hookup to the RAV. Looked around, changed a few minor things, then printed out the TPMS data. I'm hoping it will come in handy when I swap wheels and have to register new TPMS sensors.

Are you using "XHorse- MVCI" in Setup-VIM?

I think so, but can't say for sure. Would have to look. The installation does put a desktop link to the XHorse firmware update program. I didn't update, but read on-line that you can use that program to verify the driver installation.

I just saw your reply. They all need to be green to successfully reflash the PCM with new calibration files. Even as an old timer ASE Master L1 MRRT, I would be skeptical of doing this critical operation using non-approved equipment. It is very easy to brick a PCM


Registering keys and transponders doesn't use L line and K line


Can you view live data? How about actually changing some options? Certain cables look like they will change options, but when tried, an error box comes up. Other cables will not let you view live data, or go in generic.


So far, my cable of choice is the ALLScanner VCX which can be bought for less than $100 on Amazon and eBay. It does not support L Line or K Line. To get that, you need to spend about $400 and get the ALLScanner VCX Plus which is 100% J2534 compatible. But I've heard people say they can't successfully update their calibration files even with the VCX Plus since they have to get them from the Toyota website and the ALLScanner isn't on the approved list, so the reflash will not proceed.

Ya, I wouldn't try a reflash with this cable.

Volosong: I did not use ANY of the files on the CD. Everything needed (and more current versions) are available from the download links in the links that I posted.

Steve, I'm not sure what to say.
I tried the "traditional" method on an old XP machine that I had and was not able to get anything to work.
I bought the new Asus Windows-8 machine and followed the 64 bit instructions exactly as outlines in the links and everything worked first time without a hitch.
