Ultrabook Can not detect built in wireless network adapter

I accidentally deleted my wireless network adapter in network and sharing center, i couldn't get it back after trying everything so i factory reset my laptop. After the reset, still nothing shows up so i download the driver from the acer support site. When i install it thats when i notice the computer cant even detect the hardware and therefore i cant install.

Model: Acer Aspire S3-391 ultra book
OS : Windows 7 home premium 64 bit
