It doesn't wok for me I did all "Louis Davis" steps from 2 page.My Arduino Micro and Arduino UNO detects as "Unknown device" in device managerI click update driver then I select my driver location "D:\arduino-1.0.2\drivers\FTDI USB Drivers" or "D:\arduino-1.0.2\drivers"after that I have this message:I using Windows 8 purchased from Microsfot.please help.
I was motivated to join the Forum just to post this:Actually everyone, there is a much easier way past all of this. Just bypass the Digital Signature check built into Windows 8Place the mouse in the lower right corner and chose SETTINGSSelect "Change PC Settings".... then GENERAL ...... Go to the the bottom under ADVANCED STARTUP, click RESTART NOWThen select TROUBLESHOOT -------> ADVANCED OPTIONS --------> STARTUP SETTINGS and select RESTARTWhen the computer reboots, Press the key 7 for "Disable driver signature enforcement"Now you can install any unsigned digital signature. Remember this process for any future installations also.
I have come up with an alternative method to install the Arduino drivers on Windows 8.This method does not require new driver files or installation of a test signature.1. Windows Key + R2. Enter shutdown.exe /r /o /f /t 003. Click the "OK" button4. System will restart to a "Choose an option" screen5. Select "Troubleshoot" from "Choose an option" screen6. Select "Advanced options" from "Troubleshoot" screen7. Select "Windows Startup Settings" from "Advanced options" screen8. Click "Restart" button9. System will restart to "Advanced Boot Options" screen10. Select "Disable Driver Signature Enforcement"11. Once the system starts, install the Arduino drivers as you would on Windows 7
