Here's what I've done lately:
- I have tried to install the drivers on 3 different Win 10 computers. They all fail.
- On one PC I have disabled the driver signature enforcement. Still no luck.
- Uninstalled the software and tried reinstalling the Arduino file as administrator on that computer. Nope.
- Tried to right click install every file in the drivers folder. Still nothing.
The weird thing is that, when I reinstall the software after the initial install, the PC tells me that it can't even find the drivers.
Another thing, ingineer_74 says that the device is an Atmega16u2, but the chip itself says it is an ATmega328 P does that make a difference? I can't find any reference to either of those designations in the drivers folder.
I'll keep trying, for a little while longer anyway, but hopes are dimming. I really wanted this to work. Thanks for the suggestions, anyway.
BTW, following are the instructions to disable drive signature enforcement, if anyone is interested:
Perform these steps to disable the driver signature enforcement in Windows 10:
a. Go into Settings-->Update & Security.
b. Then click on the "Recovery" option on the left hand side.
c. Once selected, you will see an "Advanced startup" section appear on the right hand side. You will need to click on the “Restart now” button. The PC will immediately restart.
d. Once your Computer has rebooted you will need to choose the "Troubleshoot" option.
e. Then head into "Advanced options."
f. Then "Startup Settings."
g. Since we are modifying boot time configuration settings, you will need to restart your computer one last time.
h. Here 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.
