I can't find the arduino usb certicate for Arduino 1.6.9


I'm quit new in Arduino but i'm looking for the arduino certificate file for arduino 1.6.9 to use for the usb driver does anybody know where I can find it? To use it in an automatic installation for more then 30 computers.

Kind regards, Arjan van Wijngaarden

Allready found it by using 7zip on arduino-1.6.9-windows.exe
