# How to purchase a license
Anyone can download & install Mirae WAVE without any cost, and try it free for 14 days of evalution period. But if the evaluation period expires, a watermark image will show up on top of the main screen, and some features will be restricted. If you want to use Mirae WAVE without any of those restrictions, you have to purchase a license, following the steps below.
### 1. Visit our website for the latest information
Visit [Mirae WAVE webpage](http://www.miraeclimate.com/hp/product/mirae_wave.html#purchase), and look for the list of our sales agents. You need to select one of our sales agents and partner companies, depending on your location.
### 2. Contact our sales agent, and make a purchase
Contact the agent you selected by email. The official price of the license is **$ 5,000 (USD)**.
Additional discounts are available for group purchases. Please contact the agent for more information.
Follow his/her instructions for payments, if you want to make a purchase. After the purchase, you will be given a **_Authorization Key_** for your license, which is a 12-character string.
### 3. Perform "License Registration"
Once you have received your _Authorization Key_, you need to perform **_License Registration_** in Mirae WAVE program.
Start Mirae WAVE, click the top-left menu category in Mirae WAVE, and select _License Registration_. Enter your _Authorization Key_ into the dialog and then click "OK", and that's all you need to do. You will be notified with a message of successful registration, and later on you can always check your license information from the same menu.
Note that you need internet connection in order to complete _License Registration_. If it fails for whatever reason, please contact your sales agent.
### 4. Ask for "License Reset", only if necessary
Note that you can activate your license and use Mirae WAVE on a single computer. If you want to change computers for Mirae WAVE, or your license was removed somehow, then you need to contact your sales agent and ask for **_License Reset_**, so that you can perform _License Registration_ again with the same _Authorization Key_.
