I had the same problem with my Acer Aspire V3-571G-6602 with the same wifi adapter (AR5BWB222). I was able to get the driver to install successfully by doing the following:
Open computer management
Clicked on device manager
double clicked Atheros AR5BWB222 Wireless Network Adapter
selected driver tab
selected Update Driver...
selected Browse My Computer...
selected Let me pick from a list of device drivers...
selected Have Disk...
navigated to the directory where the win 7 driver was and installed it
(for me the path was C:\Users\myname\Documents\Drivers\Wireless LAN_Atheros_10.0.0.38_W7x64_A\WLAN_Atheros_10.0.0.38_W7x64\ndis6xWin7\netathrx)
driver date: 2/15/12
driver version: 10.0.0.38
