Windows 8 Release Preview currently blocks the installation of Arduino drivers due to a missing signature in the driver file.
The steps below will help you to install them. It involves disabling some security, so not the best fix, but if you want your Arduino drivers working quick it’s the way to go.
*update: As per the wise suggestion of commenters, I’m noting that you must save any unsaved work before proceeding and read (and/or write down) all the instructions first. The reason for this is that the second line will reboot the computer into a startup options screen.
- Press the Windows Key and the ‘R’ key simultaneously
- Copy the command inside the brackets –>[ shutdown.exe /r /o /f /t 00 ]<-- ; paste it and "ok"
- Select ‘Troubleshoot’
- Select ‘Advanced options’
- Select ‘Startup Settings’
- Select ‘Disable Driver Signature Enforcement’
- Install driver as usual via device manager
Thanks for this. Worked perfect for Windows 8 RTM. I can confirm this is a permanent fix as I feared this procedure would need doing at every boot but it’s only required for installation.
Take care, shutdown.exe /r /o /f /t 00 seems to be the reboot command, test it wisely; maybe it’s a fake.
That [shutdown.exe /r /o /f /t 00] command is correct and not a fake.
Those flags tell the machine:
/r = restart the computer
/f = force close all programs
/o = restart into options menu
/t 00 = timeout (wait) for zero seconds
But I guess I should warn people to take not of the other instructions before proceeding.
For me, it’s worked very well. But, I guess that author should to warn people to save all documents opened before.
works perfect in RTP ver 8..
pay attention.. when you hit enter..BAM.. it resets
also, instructions given are individ. menu selects
very nice..
Works great on my A6 Vision laptop with Windows 8

Hi. I doesn’t work for me. Does anybody use windows 8 with 64 bit? Does it work? I have the Arduino Mega 2560 r3. When i plug in the USB the ON an L LED’s shine red. Is this working right? The manager in control panel shows “ATmega 16u2 DFU” with yellow exclamation mark. If i want to change driver and choose the arduino/driver folder it says there are not the right drivers. Can anybody help me please? Kind regards
I’m not sure but if I have the time I’ll try to find an answer tomorrow.
Did you find a Solution?
