I downloaded TechStream 18, but it wants a key. What am I missing?
I figured out what went wrong and it's working now.

My install was based on the instructions on VXDIAG. A few things that I've changed from previous install:

1. Plugged in the dongle before running VX manager. Make sure you see the dongle in the VX manager app.

2. Do NOT open Techstream using the the real Techstream icon that was created on your desktop. You have to go to the BIN folder and use the Toyota Launcher application, it will automatically bring up Techstream. By doing it this way, Techstream no longer ask for the Key. I created a shortcut to put on my desktop so I will not need to dig through the folders to find the Toyota Launcher next time.

3. After Techstream is loaded, go to Setup>VIM Select> open the dropdown and choose TOYOTA-J2534. This is something that's not listed in the instruction but it's super important because the default is TIS Techstream VIM. If you don't choose TOYTO-J2543, your dongle will not talk to your Techstream.

4. I have a press button start car. Press the start button on the car twice. Connect your car to the dongle. Click connect to vehicle in Techstream and you should see your car's information automatically populated.

Good luck!

can’t find the icon or bin you’re talking about
 
I was stuck at getting the tech stream patch to show up....extracted driver files with winrar and at that point was able to access the patch (as seen in the installation video included with the amazon device
 
I am blown away by this VCX device!

I had spent $360 on different OBD dongles for my made in India 2011 1KD-FTV 3.0L D4D Fortuner, same engine sold on the Prado 120 and 150 here.
Found this thread, went ahead and ordered the WIFI Version VXDiag VCX NANO for TOYOTA TIS Techstream V18.00.008 - https://www.vxdiagshop.com/wholesale/vxdiag-vcx-nano-for-toyota-wifi-version.html which took 3 days to arrive.

I work in IT Networking so I already had a laptop with a VM setup with their included Techstream launcher, took a few minutes of playing around until I found the live data section, and boy, I'll let the pictures do the talking.


VCX tells me I can use the device with an authorized Techstream account to even tweak the ECU and injectors and train new pumps etc.!

this worked great. I ordered just a cheap mvci cable and used this method with the virtual box to communicate with the vehicle. I upgraded to version 18 of the techstream as well and have seen a few asking how to update. So here is how i did it. I downloaded the techstream version 18 from obdii365 blog which you can just google and it should populate once on the blog just search for techstream and scroll until you find the post for the most recent version. I downloaded the techstream v18 and the 32 bit patch to my main desktop. I then opened the xp virtual box as downloaded from here and then just drag and drop the 2 files from your main desktop into the virtual machine and proceed with the installation. Once this was accomplished i then deleted the downloads from my main desktop and just saved them in the virtual machine and it has been working flawlessly. Once you have it running in the virtual machine you only need to open the patch to pull up techstream.
 
I'm running on a 2012 MacBook Pro Catalina 10.15.7 and I can't seem to get the MVCI cable to recognize in VMWare. I've done some searching but haven't found an answer that works. Has anyone had trouble and got it working?
 
Another question on TechStream and Windows XP? A few years ago I had XP VM in VirtualBox running TechStream. It worked, but very slow and annoying. I forgot what was a reason on doing in in VM? Seems like v18 can be installed on Windows 10, it should run much better this way, right? Why people keep using VirtualBox?

Correct, just be careful which "launcher" you use, or run Techstream in a VM or on a machine you don't care about.

Why? Launcher has virus?

Highly probable especially the launcher from this link provided by VXDIAG:


It's 7 MB when other launchers can get the job done with a few hundred KB.

Download it but don't run it then check it's CRC/hash and behavior here:

Results not conclusive. Some antiviruses seem to know what it is and don't mark is a virus. Hm..

With an overwhelming majority of positives why is it worth the risk?

Like I wrote before, why does that 'launcher' need 7000KB+ of code when the job can be done with less than 400KB? What is all that extra code for?

One thing I would suggest - if you opt to use this sketchy .exe, then disable your network devices in your VM, ie don’t let it connect out to the internet, keep it isolated.
Per the malware sandbox sites I linked above, the launcher .exe from VXDIAG’s site seems a little sketchy, to put it mildly.
FWIW - I work in offensive cyber, so I’m not a blue team guy doing malware analysis. But I know enough to know that that .exe seems suspect.
 
Now at 56 pages, what is the latest greatest updatest version of techstream to acquire and install? I have the cable below but have had a long time and gave up when I could not get past the dealer ID, key, etc. Is there really a way to get this installed and working?

ok so I followed the instructions on page 1 of this thread using my Windows 10 64-bit laptop. After installation and when I try to launch Techstream I get it saying Aborted. I tried the installation twice and still the same message. Can anyone help, please?

Unless home mechanics for Toyota vehicles is some sort of high value target, my bet is the size and virus hit are related to how it was cracked to not phone home and need a key.
