How to Install Anaconda on Windows

By John Paul Mueller, Luca Massaron

You will need Anaconda to use Python for data science. Anaconda comes with a graphical installation application for Windows, so getting a good install means using a wizard, much as you would for any other installation. Of course, you need a copy of the installation file before you begin. The following procedure should work fine on any Windows system, whether you use the 32-bit or the 64-bit version of Anaconda.

1Locate the downloaded copy of Anaconda on your system.

The name of this file varies, but normally it appears as Anaconda-2.1.0-Windows-x86.exe for 32-bit systems and Anaconda-2.1.0-Windows-x86_64.exe for 64-bit systems. The version number is embedded as part of the filename. In this case, the filename refers to version 2.1.0. If you use some other version, you may experience problems with the source code and need to make adjustments when working with it.

2Double-click the installation file.

You may see an Open File – Security Warning dialog box that asks whether you want to run this file. Click Run if you see this dialog box pop up. You see an Anaconda 2.1.0 Setup dialog box. The exact dialog box you see depends on which version of the Anaconda installation program you download.

If you have a 64-bit operating system, it’s always best to use the 64-bit version of Anaconda so that you obtain the best possible performance. This first dialog box tells you when you have the 64-bit version of the product.

3Click Next.

The wizard displays a licensing agreement. Be sure to read through the licensing agreement so that you know the terms of usage.

4Click I Agree if you agree to the licensing agreement.

You’re asked what sort of installation type to perform. In most cases, you want to install the product just for yourself. The exception is if you have multiple people using your system and they all need access to Anaconda.

5Choose one of the installation types and then click Next.

The wizard asks where to install Anaconda on disk. These instructions assume that you use the default location. If you choose some other location, you’ll want to remember where you choose.

6Choose an installation location (if necessary) and then click Next.

You see the Advanced Installation Options. These options are selected by default and there isn’t a good reason to change them in most cases. You might need to change them if Anaconda won’t provide your default Python 2.7 (or Python 3.4) setup.

7Change the advanced installation options (if necessary) and then click Install.

You see an Installing dialog box with a progress bar. The installation process can take a few minutes, so get yourself a cup of coffee and read the comics for a while. When the installation process is over, you see a Next button enabled.

8Click Next.

The wizard tells you that the installation is complete.

9Click Finish.

You’re ready to begin using Anaconda.
