Error when downloading a Support Package with proxy

I'm using Matlab 2013a and I would like to install some hardware support package (for ex., for Arduino). When I try to install the package by the Support Package Installer (SPI) from Internet, an error occurs because of my proxy.

I tried to run the .p file as suggested here (<http://www.mathworks.com/matlabcentral/answers/121434-how-do-i-download-a-support-package-if-my-network-has-a-proxy>) but when I double-click on the file nothing happens and if I try to open in in the Command Windows I get an error saying that the .p file cannot be edited.

I also try to manually install the support package that I downloaded (.mlpkginstall file), but it is not recognized by the SPI (not visualized when I browse "from Folder") and I get the same proxy error as if I tried to install it "from Internet".

What can/should I do?

Thanks in advance for any help.

Problem solved: my proxy parameters were not initialized in Matlab (File->Preferences->Web). Sorry for the dummy question.
