Hi,

You can check your OS version using below steps according to your system OS:


To check your version of Linux:

At the command line, type: uname -a and press Enter. If the output contains "64" such as x86_64 or ia64, then you’re running a 64-bit system.

To check your version of Mac OS:

Mac OS 10.6 (known as "Snow Leopard") runs in either 64-bit mode or 32-bit mode, depending on the hardware in your computer. Older versions of Mac OS run in 32-bit mode. For information on how to check your version of Mac OS, see http://support.apple.com/kb/ht3696.

For Windows 8 :

1. Open the Windows 8 Control Panel.
   
   Tip: You can check your Windows 8 system type much faster from the Power User Menu but that's only accessible if you have a keyboard or mouse. With that menu open, click on System and then skip to Step 4.
   
2. Touch or click on System and Security within Control Panel.
   
   Note: You won't see a System and Security link in Control Panel if your view is set to either Large icons or Small icons. If so, find System and touch or click on it, then skip to Step 4.
   
3. With the System and Security window now open, click or touch System.
   
4. With the System applet now open, titled View basic information about your computer, find the System area, located under the large Windows 8 logo.
   
   The System type will say either 64-bit Operating System or 32-bit Operating System.

 

The above instructions are to find if your installed / existing OS is a 32-bit or 64 Bit. If you'd like to know about your processor if 64Bit or 32 Bit compatible. You can check Intel Page. Almost all models now are 64 Bit compatible and your's is a 64 Bit compatible one. A simple way is to use the Microsoft's Windows 7 or Windows 8's upgrade advisor page for 64 Bit upgrade compatibility.

Good luck!
