Hi All, I have a early 2008 macbook air with snow leopard and I want to upgrade it to Lion (on a usb stick). I wiped the harddrive clean, then boot with the stick, and chose "reinstall lion" option, but it failed with message "Failed to download additional component". I'm certain it has internet connection. I tried several times with the same error, so I googled a bit, and some people say it works if upgrading from SL (rather then from a wiped HD). So I reinstalled SL and try again, but still the same error. Before I make a trip to Apple store, i want to ask if anyone has resolved this particular issue before. Thanks in advance for your help!
