Error with verifying with new IDE v1.6.9

Official Hardware Mega Due
1

I just downloaded and installed Arduino.zip file. All other CPUs work but DUE doesn't. This is the message.

Arduino: 1.6.9 (Windows 7), Board: "Arduino Due (Programming Port)"

Board arduino_due_x_dbg (platform sam, package arduino) is unknown

Error compiling for board Arduino Due (Programming Port).

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

Please note that I'm just verifying, nothing is uploaded or connected.
The sketch is simplest possible

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:

}

Edit: I just download the install version. This same bug is there too

Hello LMI:

Did you have to install the Arduino Due package?

If your answer is no, here my recommendation:
Make a backup of you Arduino libraries and then proceed to delete the libraries folder (C:\Users\UserName\Documents\Arduino\libraries).
Uninstall your all the Arduino IDEs.

Install again the Arduino IDE 1.6.9 using the .exe (not the .zip).

After installing the IDE 1.6.9, not Arduino Due board should be reach. Then, click in Tools -> Board: "Arduino/Genuino Uno" -> Boards Manager...and install the Due package (you'll need Internet connection for this). Regards,
