Last Updated: Mar 09, 2018 04:41PM MST

This article describes how to Download, Install, and License HOMER Pro.

How to: Activate a Purchased HOMER Pro license from a trial. 

To download HOMER Pro you must first Log In or Create an Account. You can accomplish this by clicking on the “CUSTOMER SITE” tab on the top right of the HOMER Energy Home Page or by clicking on one of the many “21-Day Free Trial” links around the website.


If you are a new user and you are creating an account for the first time please go through the user registration process and confirm your email address. You will then be asked to complete your user profile with further questions before you can download the HOMER Pro software.
If you logged in through a “21-Day Free Trial” link you will be directed straight to the HOMER Pro download page. If you logged in through the “LOGIN” tab simply click on HOMER Pro to reach the same page. Read and Agree to the “HOMER End User Agreement” and click the “Download HOMER Pro” button to begin downloading the latest version of HOMER Pro.

See 64-bit or 32-bit HOMER Pro, which is right for you?


Once the software has downloaded, open the install file named “HomerPro-X.X.X.msi” to begin the installation process.

The HOMER Pro Setup Wizard will guide you through the process.
If you are attempting to run HOMER Pro on Windows 7 and the installation fails please see Fixes for Windows 7: the .net Framework.

First time HOMER Pro users are eligible to try out our software free for 21 days. The trial will include all modules and will be fully functional. If your work requires saving your data, please look into our full license options.
When you open HOMER Pro for the first time, it will ask you for your email address. Clicking on the box “Create Free Trial" will automatically download the license file through HOMER Pro or direct you to purchase a license. 

After you have purchased a license, select "Activate Paid License" where you will be directed to our website. Please follow the remaining steps on the license panel to retrieve your new license. 

If the automatic download is blocked by a local firewall, HOMER Pro will direct you to a page where you can download your license file. Please put this file into the folder located at Documents/HOMER Energy/License. Once you put the license file in the correct destination, restart the software. You are now ready to start using HOMER Pro to model microgrids.
