# 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.
