ArcGIS 10.x installation instructions for students

This tutorial will help you install ArcGIS 10.x on your Windows operating system. Please request a license code before beginning the installation process. If you are a Mac user, please read this page about running Windows in OS X before requesting a code. If you are seeking to reinstall your already-licensed copy of ArcGIS on a new machine, you will need to deauthorize your license on the old machine first. Please read this page for instructions on how to do so.

For users reauthorizing copies of ArcGIS already installed on their machine, visit to register your license code with Esri, then open ArcGIS Administrator (located in the ArcGIS program group in the Start menu). Click on the Desktop folder in the left-hand pane, select the Advanced (ArcInfo) Single Use option, then click Authorize No​w. The reauthorization procedure will be similar to the process that begins in step 8. 

  1. After filling out the ArcGIS license request form, you will receive an email from a Map & Data Library staff member with an authorization code that begins with EVA. This code will be used to activate your student edition of ArcGIS, and will time out 365 days after installation.
  2. Go to and log in with your ESRI Global Account (create a new one for yourself if necessary). After logging in, you will be prompted to enter your evaluation code.
  3. On the following page, you can choose a version of ArcGIS to download if you do not already have it installed on your computer. If you are using ArcGIS to complete assignments as part of coursework, please check with your instructor to find out what version you will be using in the course before installation. Download the ArcGIS for Desktop installer to your hard drive. You may also wish to download ArcGIS Data Interoperability for Desktop if you anticipate using data formats that will require conversion.

  13. The wizard will then connect to ESRI to authorize the software. You should receive a message confirming that the installation was successful. Click Finish to complete the installation process. You will now be able to use the software for 365 days. If you downloaded the Data Interoperability installer in step 3, you can now proceed with installing that extension separately.
