    Copy the license.txt from your old PC to your new one to be sure that it is formatted right.

    Um, It does not allow me to copy the text?

    I tried entering it again and same thing? I dont get it, there must be something else I am doing wrong ?

    This really isnt complicated I am just entering the numbers and letters
    but it is frustrating

    Remove the license.txt located in
    C:\Documents and Settings\Administrator\My Documents\EFILive\V7.5\User Configuration of your new PC and replace it with a copy of the one from your old PC.
    This will remove any and all doubt whether or not it is formatted right.
    If you get the error with one PC and not the other, then it must be
    the license.txt

    Have you flashed your truck before?
    The license for the software in not the same as a license for the PCM.
    The PCM license is in the Flashscan device itself.

    Post a shot of the error.

    This is a really old thread and I remember USB FTDI driver issues for everything back then.

    But is there any issues with drivers today? EFI Live can not find my RR, but all drivers are running other Moates devices and all my cables. No issues in years.

    Yes, uninstall the latest FTDI USB driver and install the older one


    Start->All Programs->EFILive->V8->Tools->USB Manager

    I have no old drivers after the laptop crash. Do you know what driver is needed so I can find it?

    EDIT V2.02.04 is an option in V8 USB drivers, is this the one?

    The old/new drivers come with the EFILive software install.

    And it works with VCP checked. EFI Live found it, now I just need the license...

    Is there anything you can't fix Joe?
