Error message when uploading

Hi everyone . I bought an Arduino Uno 2 days ago and I never was able to upload anything to it .
I try to upload the sketch Blink , the rx led blinks 3 times , then I get an error ( I will post it below)
The arduino has the drivers , the COM port is the right one , the board is "Arduino/Genuino Uno" .

Here is the error :

Arduino: 1.6.11 (Windows 8.1), Board: "Arduino/Genuino Uno"

Sketch uses 928 bytes (2%) of program storage space. Maximum is 32,256 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes.

avrdude done. Thank you.

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

Also , I'm using the ArduinoISP programmer .

Hi,

Sorry I was unable to help more, and it's a shame you've received so little help on this forum. Here are a few more places you can go to seek help:

Luck to you,

I don't use the ISP programmer, but this is sometimes seen when the device driver is not installed. Look in the drivers directory of your IDE and trying running the appropriate installer.

The OP posted about this a few days ago but received no satisfaction, despite my best efforts. Strictly speaking, this a cross post, but I'm sympathetic since he's clearly desperate and the previous thread dried up. Here's the original with the history of what's been tried:
