I basically have the same problem as the person in this link
https://forum.arduino.cc/index.php?topic=427154.0
I decided to make a new post since the thread was last active a few years ago.
I'm trying to install Arduino Mega and Arduino Uno support packages for Matlab R2012b but I keep getting the following error:
"Cannot download http://arduino.googlecode.com/files/arduino-1.0-windows.zip: Error downloading URL. Your network connection may be down or your proxy settings improperly configured.."
I tried to check the download link "http://arduino.googlecode.com/files/arduino-1.0-windows.zip" but it appears to be down.
Someone told me that the correct link is "http://downloads.arduino.cc/arduino-1.0-windows.zip", but I do not know what to do once I have downloaded the file.
Thank you!
