Silent install of Arduino Drivers on Win7X64

Using Arduino IDE 1.x
1

Hi hope someone can help.
I work for a university and want to push out drivers for Arduino UNO R3 boards to student labs.
The students don't have admin rights on the Windows 7 x64 PCs.

I'm trying to use Dpinst-amd64 in silent mode AFTER I've imported the three security certificate into Trusted Publishers;
Adafruit Industries
Arduino LLC
Arduino srl

Everytime I run the silent install, it still prompts me to 'Would you like to install this device software?'

Name:Adafruit Industries LLC Ports (COM & LPT...
Publisher:Adafruit Industries

Even though the security certificate ARE already in the Trusted Publishers;
I do notice Adafruit Industries expires on 12/01/2020
and Arduino srl expires 06/01/2019
BUT
Arduino LLC expired on 18/01/2017 ! :frowning:

Thinking this is my problem, how do you a get a new signed certificate?

Many thanks for any help

ok looks like I was doing everything right, it's a bug in Windows 7
Some of the certificates are chained to Symantec Class 3 SHA256 Code Signing CA

The SHA256 is the significant bit, without the patch below, even though the Arduino srl certificate is in the "Trusted Publisher" Windows ignores it until the patch is installed and the PC is rebooted.

unfortunately you can only get this patch by emailing MS see;

Windows6.1-KB2921916-x64

I also found as I only want to install the driver for the Arduino R3 board I removed all other drivers except arduino-org.inf and arduino-org.cat

Happy days
