i use window7, an i have the arduino uno R3. It is the first time i use Arduino uno.
when i followed instructions to update drivers, i did not see the arduino.inf file, but instead the drivers file itself.i took the drivers files and the computer starts recognising my board under COM34.
It is ok when a click on verify but while cliking on upload i receive the folowing message:

Arduino: 1.6.6 Hourly Build 2015/10/21 05:53 (Windows 7), Board: "Arduino/Genuino Uno"

avrdude: ser_open(): can't open device "\.\COM1": Le fichier spécifié est introuvable.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

This report would have more information with
"Show verbose output during compilation"
enabled in File > Preferences.

how can i solve this problem?

I have forgotten to say that the LED at pin 13 is blinking whereas i have never load a program. is it normal?

Many boards have "Blink" loaded on them at delivery to show it is alive when you get it.

You say your computer recognizes the board as COM34, however that error indicates that it's trying to open COM1, which probably doesn't exist at this point. From tools -> Port menu, select the port that corresponds to the board - if no ports are shown there, you may have a driver issue.
