Installed on a Win 8 pc with AMD processor this evening. I ran into the same problem as 5113wg did. Seemed to freeze up and do nothing. Just let it sit for about 20 min and the install menu did finally appear. Clicked install and it took about another 20 minutes to install software. I rebooted and plugged in the transmitter USB and waited another 20 minutes for it to ask for both codes. No big deal just make sure you are not in a rush.
