Netgear A7000 WiFi Adapter unable to be detected

I just bought the adapter today and tried installing it on my Windows 8.1 Desktop PC. I followed the directions on the manual and installed the Windows Adapter Software and clicked on Check for Updates. Then it downloaded the latest version of the software which I installed, but when it asked me to plug in the adapter and press Next, I plugged it in and pressed Next, It says it is detecting, but after a few minutes it says it can not detect the adapter when I have it connected. I have tried reinstalling, rebooting, nothing changed. I went to Control Panel's network adapter settings to realize it is not enabled, as I tried to enable it it can not be enabled. Though in the Devices list it has been recognized. I am currently using the 2.5GHz network with my on board card but I need the 5GHz speed as it is the sheer reason I bought this adapter. But unfortuanetly it has not worked.

If anyone can help me I would thank you greatly!
