How can I determine whether or not I am running a 32-bit or 64-bit Operating System?

I would like to download MATLAB, but I am unsure of whether or not I am running a 32-bit or 64-bit Operating System. How can I determine this?

To determine whether or not you are running a 32 or 64-bit Operating System on Windows, follow the instructions below:

For Windows operating Systems, see Microsoft's KB article here:

https://support.microsoft.com/en-us/windows/32-bit-and-64-bit-windows-frequently-asked-questions-c6ca9541-8dce-4d48-0415-94a3faa2e13d

For Mac OS X, you are using a 64-bit capable operating system if you:

1) Have a 64-bit Processor. See Apple's support site here to check your processor:

2) Are running OS X 10.5 (Leopard) or higher

NOTE: For MATLAB, if you want to use 64-bit MATLAB, you will need to have 64-bit Java installed (Java version 1.6 or higher). For this you will need Leopard 10.5.5 or higher.

For Linux operating systems, you will want to run the following command in a terminal:

uname -a

If your output includes the tag "x86_64", it is a 64-bit operating system. Otherwise, there will be an "i686"," i586", or "i386" tag, indicating you are running a 32-bit operating system:
