32 Bit vs 64 Bit

Technical Support
I am just wonder if I can play World of Warcraft on a 32 Bit computer, I am currently on my Laptop with 64 Bit but it says my new computer is 32 Bit, Can I download it? If not can I upgrade my computer to 64 Bit?
The standard game client is 32 bit. You have to actually install the 64 bit files and then use the 64bit launcher to play in 64 bit. Just run the regular launcher.exe and you will start in 32bit.
To use the 64-bit client, both the hardware and the OS have to be 64-bit. Any computer made within the last 5 years is going to have 64-bit hardware, but it's possible you have a 32-bit OS. 64-bit computers can run a 32-bit OS, but a 32-bit OS cannot run 64-bit software even if the hardware supports it.

If you want to see if your OS is 64-bit or not, right click on either "My computer" (Windows XP) or "Computer" (Windows 7) and click properties. If it is 64-bit, it will say 64-bit OS in the description. If the OS is NOT 64-bit, you will need to get the 64-bit version in order to run 64-bit software. A 64-bit OS will not run on 32-bit hardware, but a 32-bit OS WILL run on 64-bit hardware. But, as I said before, any hardware made within the last 5 years is going to be 64-bit anyway.

If you are getting a message that you have a 32-bit operating system installed then you actually do have a 32-bit operating system installed.

The 64-bit client is going through testing, you can use it, but its not really supported.
Thanks for all the information guys, I really appreciate it! :)
So it said I had 64-Bit OS so that means I will be able to run Mists of Pandaria on it, right?

Um, MOP does not require 64-bit to run. It SUPPORTS it, in the same way that the current live client supports 64-bit if you want to enable it, the difference being MOP will have the 64-bit client available by default (you won't have to download extra files).

But if you have a 64-bit OS/hardware, there is really no reason to not use the 64-bit client.
