I've downloaded the WIndows version of the Arduino/Intel IDE (Arduino Software 1.6.0 - Intel 1.0.4) from this page Intel® Galileo Boards — Software Downloads but the file won't open. WInZip and other Unzip applications that should be able to open a ".7z" type of file all tell me that the file got from the website is not openable. I've re-downloaded the file but that didn't help. It's still unopenable. Can anyone suggest a solution?
