avrdude: stk500_recv(): programmer is not responding

Using Arduino IDE 1.x
1

Hello:

I have seen some topics about that but none of the answers work for me.

I have a Windows 7 and Mega 2560 on Port 5 (previous attemps with other Mega 2560 in Port 4).

I was running IDE 1.0.5 and today i installed 1.6 in a different folder.

With new IDE i get the following message:

System wide configuration file is "C:\Program Files (x86)\Arduino/hardware/tools/avr/etc/avrdude.conf"

Using Port : COM5
Using Programmer : arduino
Overriding Baud Rate : 115200
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x01

Back to old IDE and everthing runs fine.

I tried reset, re-starting IDE and Windows, de-installing and installing againg Arduino 1.6, etc. Nothing.

I tried to point Windows to the new driver: windows tells me that the driver is the most updated.

What can you suggest?

I should add that getting properties of the driver installed, Windows tell me that it is version 1.0.0.0 dated 04/01/2013.

I tried repeateadly to change to the driver in the new drivers folder I have just installed (dated 08/february/2015) by desinstalling old driver and indicating Windows to seach in the driver's folder: no way, it instalsl always version 1.0.0.0

Could this be the problem with the new IDE 1.6, not loading sketches?

How can I change to the new driver?

problem was the selected board was marked as UNO and I had a Mega.I changed it in Tolls/ Board and everything is OK.
