# PSPP for Beginners: Obtaining PSPP

## How to download the software

The official web site for PSPP is GNU PSPP. Before downloading, it's worthwhile to browse the official site and learn more about PSPP.

When you're ready to try it, the next step is to install it on your own computer. PSPP can be downloaded for free from the Free Software Foundation. The Obtaining GNU PSPP page has links to various download locations.

## Which version do I need?

Most students will want the "binary" version: a compiled program that is ready to be installed. The binary software is variously called a package (Linux), installer (Windows), or bundle (Mac). Choose the version that is appropriate for your computer's operating system.

The download page also has source code: computer programming instructions that are used to create the software. Most students will not need the source code.

Another choice is between the stable or development versions. The stable version (1.x or higher) is an older version of the program that has been thoroughly tested and proven. This would be the best choice for most people. The development version may offer newer features, but the downside is that this software might be more unstable.

Windows users have a choice between 32 bit and 64 bit versions. The 64 bit version is the best choice for most people. Choose the 32 bit version only if you have a very old computer.

## Installation tips

Download the installation software to your computer from one of the sources provided at the GNU PSPP download page. Follow the guidance from the installation steps.

Administrative privileges may be needed on some computers to install software. MacOS, in particular, may balk at running the installation software because it comes from an unknown or unsigned source. The solution is to give the application proper permission to run, even though it is from an unsigned source. This support article from Apple explains how to give this permission.

## Systems that cannot run PSPP

PSPP cannot be installed on ChromeOS devices because there is no web-based version of the software. Windows PCs that require the Microsoft Store may also be problematic because the software might not be available from the Microsoft Store.
