How to Disable Driver Signature Verification on 64-Bit Windows 8.1 or 10
To disable driver signature verification, we’re going to need to get into the Troubleshooting options from the boot manager. The easiest way to bring this screen up is using a secret trick.
Simply select Restart from the power options menu (on Windows 8 that’s under Charms or on the login screen, and in Windows 10 it’s on the Start Menu).
Hold down the SHIFT key while you click Restart.
(Again, you can use this trick on any of the power menus in Windows 8 or 10, whether on the login screen, Charms bar, Start Menu, or Start Screen)
Once your computer has rebooted you will be able to choose the Troubleshoot option.
Then head into Advanced options.
Then Startup Settings.
Since we are modifying boot time configuration settings, you will need to restart your Computer one last time.
Finally, you will be given a list of startup settings that you can change. The one we are looking for is “Disable driver signature enforcement”. To choose the setting, you will need to press the F7 key.
Get to the desktop and plug in the tiny AVR board.
Open the device manager by right clicking on the windows start button in lower left corner and select device manager.
You should see FabISP under Other Devices.
Double click it and update driver then choose Browse My Computer for driver software and click Browse.
Now go to your downloads or where you saved it and select that folder (usbtinyisp_libusb-win32_220.127.116.11) .
Select it and click ok.
Windows will warn you “Can’t verify publisher of this software”, go ahead and click “install this driver software anyway”.
Click next and this will install the driver software for the card.
If it was sucessful you should see.
When you go to close the device manager you should see this. USBtiny
Now we need to configure the Arduino software.
Now go into the arduino software and click Tools – Programmer and select USBtinyISP.
Go back to File – Preferences, click on the rectagular icon, hit return, then on the next line paste in this link.
You need this link (copy it)
