virtual box not supporting 64 bit os

I recently downloaded Kali Linux from Offensive Security and installed it into Virtual Box. I had specifically chosen the 64 bit version as I had assumed my Windows 7 OS with an Intel Core i3 was 64 bit, though upon configuring the General settings all the Linux operating systems listed came out as 32 bit, though I had checked earlier that I did indeed install the 64 bit version from the website.

It seemed to work fine at first, as I made it to the Boot Up menu of Kali and chose Install, however the process never works because the Boot menu keeps giving me a message stating:

This kernel requires an x86-64 CPU, but only detected an i686 CPU.
Unable to boot - please use kernel appropriate for your CPU.

Under System Settings of Virtual Box I noticed under the Processor tab that the CPU was locked at 1 and I had no access to the Acceleration tab. I tried looking through for a solution on Youtube, where some tutorials suggested PAE/NX might help, though in my case it didn't change the CPU error.

Could anyone here please help me with this issue, as I really wish to be able to use Kali.

I know this is an old question, but my question back to you would be, is the OS you are running on 32 bit or 64? If its 32, you won't be able to run a 64 bit os, even in a virtual environment.

To find out if your Windows version is 32-bit or 64-bit, type on a command line:
Expand|Select|Wrap|Line Numbers
  1. wmic os get osarchitecture
your should get an answer like this:
Expand|Select|Wrap|Line Numbers
  1. C:\Users\Luuk>wmic os get osarchitecture
  2. OSArchitecture
  3. 64-bit
