Tools -  Boards   -    Arduino UNO

Hello everybody, I have a problem with the software arduino0021

because I can't choose in TOOLS - Boards - Arduino one :-[

I just can use: Arduino Duemilanove ..... ATmega 328

but obviusly it will have problems uploading any program.

I think that it is because I have Windows 7 Home premium and it is

64 bit. Indeed I have one Arduino Duemilanove and I don't have such

a problem like that.

Could someone help me with that?? :-[

Post a screenshot of what you see when you click Tools > Boards. I have the same OS as you and I see Arduino Uno as the very top item in the Boards list.

here is my screen

C:\Users\Javis\Desktop\screen.jpg

mmm problems adding the screen...

but at the top is: Arduino Duemilanove ..... ATmega 328

and the others, there is no Arduino Uno board as option :cry:

I have tryed with another computer with windows Xp and I

can choose Arduino Uno, and everything is perfect, eventhough

I don't have that option in my windows 7 (64b) Pc... :-[

You got the latest IDE on this computer? Sounds like you have an old one.

Download the latest one (0021) from the download page and install that. If you already have that then re-installing may fix the issue anyway.
