Trying to install an upgrade from Windows 7 to 8.1 using Parallels Desktop 10

I'm getting this message:
You can't install Windows 8.1 because your processor doesn't support NX

According to my MacBook Pro's specs (Retina 15" early 2013, 2.7 GHz Intel Core i7, 16 GB 1600 MHz DDR3, NVIDIA GeForce GT 650M 1024 MB) it should be able to run. Is this actually the case or are my machine's specs not good enough? If they are, how do I get past this error?

Thanks, all!

Hi
I have exactly the same error message. I have 8GB of ram and my MacBookPro is 2011/12 model, so its fairly new.

I've followed the above instructions from Ram, and it doesn't work.

Ram, i think you were the support engineer to assist me with this: I downloaded the ISO file, and I get the same error message. I tried your instructions above also (in this thread), and it didnt make a difference.
