Techstream v14.30.023 Unable to connect to VIM - Windows 10 64-bit

** Generally speaking, don't upgrade the firmware on the mini-vci cable/dongle. You also don't need the latest and greatest version of techstream for your current gen2, though some versions have features that others may not.

Nice to see that you've entered the water with a full back flip and a double twist

Doubtful if this will be a simple drop down menu install. I've pulled off a winblows 7 install before, and I'm pretty sure 8 and 10 are equally as doable.

Though we should have this sorted. In the future please use the advanced search feature within the forum, as it's currently working.

Give the link below a shot, and let us know how it works out. Scroll down until you find " Techstream install windows 10: "

Good luck

 

The problem is the driver for the mini VCI cable there is a way to edit your configuration and get the driver to install on 64-bit windows. A buddy who is better with windows than I am did it for me in 5 minutes. It's just that you are trying to install a driver meant for 32-bit on 64-bit. Do some Google searching and you will figure it out

 

Travis, I want to talk to your friend. I am very familiar with Windoz and I have been unsuccessful for years in getting this to work with W10 x64. I have it working on W7 x32. I have tried EVERYTHING. Step-by-Step instructions, AutoKent, registry hacks, TS versions 8, 10, 12, 14, driver version 6, 10, 12, and a clean install of W10. Nothing works. The FUT absolutely doesn't work on x64. and the reference to is in the write-up for getting it to work on x64 makes me believe whoever wrote it has no clue.

 

I get a security warning when I click on that link.

 

Forgive me, but did you have any interest in entering sensitive information, like a CC or SS# on that website?

If not, then you might try using a different browser, or just hit the "advanced" button, and allow an exemption for this session.

 

Or downloading software from it to run on your equipment?

 

I don't believe there is downloadable software being hosted on that website. Simply visiting or reading that website, or any other with a self signed / out of date SSL/TSL certificate isn't anything to be overly concerned about, even if drive-by downloads are real.

Now if someone wanted to make an online purchase or enter personal details, they might want to take pause, and even if shenanigans presented themselves, it would only take a simple call to the CC company to sort out the unwanted account activity.

Real world safety or risk thresholds vary per individual, some will never use online banking or even consider shoping online with a debit/CC, and others see no issue with doing either. This is why there are 'walled gardens' of all types, it takes the perceived risk out of the process. Though most will believe what big tech/brother tells them, it may not always be in their best interest.

 

I looked at the link ending in -download-and-install and a made an nice-person-umption.

 

Just installed the latest Techstream (v16.00.017, 2/2021) on Win10 on my several years old ebay Mini-VCI J2534 dongle. Also got stuck awhile with no VIM communication. Got it working. Here are some tips.

A. Need 3 pieces of software : Techstream of course, a 64b VIM driver, a USB to serial driver for your dongle

B. Used Autokent's 64b MVCI MultiDriver, search on mhhauto.com. Including drivers for several version of firmware on dongles. Install with admin permission on W10. Anti-virus will flag trojan but I told it to accept it. Never had a virus problem but its a Win10 partition I use strictly for electronics diagnostic purposes and no personal info.

C. I read most Chinese Mini-VCI J2534 are FTDI chip so need their USB to serial driver. Here is the installer + page its on
https://www.ftdichip.com/Drivers/CDM/CDM21228_Setup.zip
VCP Drivers - FTDI (ftdichip.com)

After installing this, Device Manager will show USB to Serial device (COM3 for me)

D. Activate Techstream via various methods depending on where you got it from.

E. After all 3 installed
Run MultiDriver and install the a matching dongle firmware version driver. I just picked the latest
Plug-in dongle, put Prius in accessory or ready mode
Run Techstream and select the matching VIM version installed by MultiDriver
Connect to vehicle

I was stuck unable to communication to VIM without step C and worked fine afterwards.
