Help me please downloading the emulator

So, when i try to download the emulator through my browser, it doesnt work. I try different browsers, everything! It says the server ip cannot be found :(.

This URL doesn't work for you?
http://appinv.us/aisetup_windows

It does work, but the thing says "The app inventor thing has been downloaded for all uses before, please restart with admisnstator privlages" but i have adminastraotr privlages because im the only one using this laptop. (sorry if i made spelling errors, i cant spell)

The link Abraham provided does not point to the emulator instructions Instructions

Just because you are the only one using the laptop does not mean you are loading the setup software with Admin privileges' Bobbert/.

Uninstall the emulator, then right click on the ...win_setup.exe to get this pop up

RunAsAdministrator
then left click on Run as administrator
