Windows 8 Forewarning

Just setup Windows 8 - some neat stuff, a bit of a learning curve. Unfortunately, Mission Planner came up just fine, but I could not get Mega2650 drivers to load so there is no connection. So, before you do a one way upgrade, be careful.

I tried the drivers in several Arduino versions with no luck- if anyone has a link to a working Mega2650 driver that would be great!

  • can you tel me the link to the new Driver for windows 7 and windows 8.

  • The driver enforcement policies for Windows 8 are much stricter then Windows 7 - thus the challenge with some Windows 7 driver installs under Windows 8

    You can try this....it might help you....


    This method does not require new driver files or installation of a test signature.

    1. Windows Key + R
    2. Enter shutdown.exe /r /o /f /t 00
    3. Click the "OK" button
    4. System will restart to a "Choose an option" screen
    5. Select "Troubleshoot" from "Choose an option" screen
    6. Select "Advanced options" from "Troubleshoot" screen
    7. Select "Windows Startup Settings" from "Advanced options" screen
    8. Click "Restart" button
    9. System will restart to "Advanced Boot Options" screen
    10. Select "Disable Driver Signature Enforcement"
    11. Once the system starts go to Arduino/Drivers folder and right click on the Arduino device you have and select install.

    Or Try this...but this was for Developer Preview days and my guess is it may not work anymore....


    I think you should be good to go then.So, one of the big issues I’ve had with the Windows 8 is that Microsoft now not only forces you to use Digitally Signed Drivers (this isn’t new, as Windows 7 requires them as well), but also checks to see if the driver has been modified and will fail to install if it has.

    This is a problem for anyone who needs to modify a driver .INF to support their device (*cough*Android ADB Drivers*cough*). Fortunately, there is a (slightly complicated) workaround.

    To get started:

    1. From the Metro Start Screen, open Settings (move your mouse to the bottom-right-corner of the screen and wait for the pop-out bar to appear, then click the Gear icon).
    2. Click ‘More PC Settings’.
    3. Click ‘General’.
    4. Scroll down, and click ‘Restart now’ under ‘Advanced startup’.
    5. Wait a bit.
    6. Click ‘Troubleshoot’.
    7. Click ‘Advanced Options’
    8. Click ‘Windows Startup Settings’
    9. Click Restart.
    10. ???
    11. Profit!

    When your computer restarts, select ‘Disable driver signature enforcement‘ from the list. You can now load your modified driver. Reboot again once the driver is installed and all will be well.

    Update (June 5th, 2012): As requested in the comments below, you can permanently enable Test Mode () by opening an Elevated Command Prompt and typing the following commands, then rebooting:

    bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
    bcdedit -set TESTSIGNING ON

    To turn it off again, use these commands:

    bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS
    bcdedit -set TESTSIGNING OFF

    Standard disclaimer that by enabling Test Mode you are opening yourself to potential maliciousness, blah blah blah. I’m going to assume that if you’re going to do this you’ll have the common sense to verify things before installing them. Don’t blame me if your computer bursts in to flames!
