    I purchased a 3rd party OBDII with TechStream to try to program a new smart key for a recently purchased 2010 Prius.


    Unfortunately the installation instructions are thin and I am having repeated issues with the MVCI Driver aborting installation prematurely. This has happened on multiple attempts on 2 different laptops.

    The Techstream is version 12.xxx, so it should work on a 64-bit machine.

    I emailed the seller and they sent a link to another package that appears to be the same or similar software that came on the CD with my Dongle, but when I try to download it I get multiple warnings that it could be a trojan and Chrome actually wont' let me save it--it just gives a 'remove' option, which I'd never seen previously on many other downloads.

    Has anyone else seen this specific issue and have a work around for it?

    I am interested in how you resolve your issue. Yap, I had similar driver issue when I tried to install MiniVCI I purchased from eBay. Can't remember what Techstream version it came with. The Techstream program installed fine, and the registration was also OK so I could use the software on my 32bit Windows 7 Netbook. However MiniVCI was never recognized by the computer. No solution was found for my case. I did purchase different MiniVCI since then, but have not tried it yet.

    Yes, turning off AntiVirus will likely to give you way to access and download the file. My problem was not in downloading, but recognizing Mini VCI. I think I have an issue with the driver compatibility. That said, those pirated software are known to have serious virus with them, so be careful when downloading and opening it. I did it with a very old isolated Netbook which I have absolutely no important personal information on it.

    2010 Prius IV that will be my daughter's car when she gets her license in ~15 months. In the mean-time it's our "gasser" for the few routes that are still difficult around us for the Teslas.

    I’ve got an old laptop and an older version that works well.

    It’s version 10.30.028 and once you put the software key in and remap the driver, you’re good to go.

    Update:
    Uninstalled anti-virus and turned off my spam blocker on my old laptop, rebooted and tried to install the driver, and the exact same thing still happened, the process aborted prematurely.

    Raytheeagle, I don't know what "remap the driver" means.

    A bit of an extra step but I had a similar issue with Norton flagging some of the drivers for unknown viruses. I actually sent Norton the files in question and they checked them and the whitelisted the files = no more issues. Turnaround was about 24 hours.

    I’m not a software engineer but it appears some drivers can appear to the virus scanners as having properties similar to viruses but are not actually infected.

    I'll double check that there isn't another anti-virus running. But I'm pretty sure I removed everything except Kaspersky previously, and now that's gone too. Should be clean (in case anyone's wanting to hack me...)

    It’s a step on the video they typically send were you take the executable file and drop in the other one.

    I don't remember seeing that, but the video I got was really hard to follow, so it is entirely possible I missed something. There is an .RAR file that I'm not sure what to do with, so there may be something there.

    I’d watch the video again and make sure all the steps are followed.

    I had to watch it a couple times and pause it to ensure I did it right.

    But now it’s one of the best tools I have now that it works(y).

    Have your kids whatxh the video and tell you what to do step by step.
    Kids don't miss stuff.
    Especially when the get to tell the parent what to do. Or point out that the parent is not properly following directions.
