Error uploding blink example.


I'm new with arduino, and I'm following the steps in the book.
But when I try to upload the first example (the blink exmaple) its says that there is an error with compiling the programm.

Can you please help me.

My SO is Windows 7 Professional 64 bits
I have a Arduino Uno (the one that comes with the starter kit)
I haven't uninstall any software in my computer, just connect the arduino board to start using it and got stuck here

This is the error that I'm receiving

Arduino:1.6.4 (Windows 7), Placa:"Arduino Uno"

collect2.exe: fatal error: cannot find 'ld'
compilation terminated.
Error de compilaciĆ³n

I dont know if this help but when I connected my arduino for first time the green led turned on and also the led with the "L" marked on a side.

Thanks in advance.
