    I'm sorry but I don't understand what you're asking.

    Have you installed VCM Suite?

    What is asking you what you want to open the program with? What are you clicking on or trying to open?

    Lots of people are willing to help but try to remember we can't see what you're seeing so a really good description or screenshots go a long way

    Good morning everyone,

    I am new to the forum, but have had a tuner for some time now. I am trying to install the MPVI drivers onto my newer computer and I keep getting and error code 52. This code says "Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.(code 52)". I have tried to update the drivers over the internet and all it does is stay on the searching screen. I have also tried updating the drivers by search the cd and it says the drivers are up to date. Sorry this is long. Does anyone know what to do?

    Got a new computer and Im having a repeated, very annoying issue.

    The interface loses connection to the PC and then wont connect to vehicle.

    With internet and the mpvi plugged in, I cannot resync the interface, it cannot be found.

    Attached screenshot of drivers.

    Restarting computer with network connection has fixed the problem at least once, so that I could resync...leave the MPVI plugged in though, and 3 hrs later it wont connect to my car again. I know it?s an interface to computer issue based on the behavior.

    Any thoughts on how to avoid this behavior, or a sure fire way to correct it when it happens?

    I am a computer novice beyond operating software.

    I would try on an alternate pc to rule out a pc issue, if you still have the issue I would suggest trying a new USB cable. If you are able to recreate the issue on two pc's with two different USB cables I would suggest contacting support and we can have you send in your interface for testing.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    Thanks so much for the response Bill.

    I am leaning towards it being a PC issue at this point.

    Are there any basic places to start looking at that fix though...(I know yall arent PC hardware people per se, Im just lost and not sure really how to even phrase my issue to people smarter than I on this subject)

    It seems like my computer is kicking out the drivers, or similar, and decides to disconnect the MPVI (its not just this USB device that has been a little wonky on this new PC).

    Another wrinkle...I restarted comp again with usb plugged in and on network cable. I could not resync the interface through scanner...go to editor and it resyncs right away, go back to scanner and it now sees the interface...weird?

    I just upgraded my laptop running windows 7 with a SSD hard drive and more Ram, tried to connect and got the "VCM Editor has encountered a problem...object inference not set to an interface of an object"
    Removed VCM Suite and deleted drivers, performed re-install and drivers {Drivers only appear when cable is plugged in?} Operating system still the same, but won't connect???
    I did the same on an older laptop running XP that I had HPtuner running on and it shows the drivers above the correct location and when I try to update them..it fails to perform that task, and just won't update?
    But I'm really more concerned with my newer laptop running windows 7....very frustrating. drivers are in correct spot, new install...and nothing...similiar issues
    Are the drivers store in the cable or supposed to be visible when cable is not plugged in?
