# Registering Iota license

**Description**

This section describes the steps to register a license for Iota:

## Local license

1. Go to Windows **Start Menu** and inside the **Iota** folder, click on **License Registration** icon.
2. After a few seconds, a new tab with the **hostname** of your machine and some instructions will be open in your default web browser.
3. **Copy** the **hostname** shown in the window and **email** it to <info@particle-analytics.com> to get your license file
4. Once you have received your **license file** from our team, **copy** it to the **`AppData\Local\ParticleAnalytics\Iota`** folder located at your home directory (e.g. `C:\Users\Stephen\AppData\Local\ParticleAnalytics\Iota`).
5. Please, change the name of the license file to **`particle.lic`** if the name of file is different.
6. Go to Windows **Start Menu** and click on **Iota Jupyter** icon to launch Jupyter Notebooks and start creating a new iota notebook

## Floating license

Iota supports floating licenses using the license server developed by Reprise Software Inc. For information on how to install the license server, please contact <support@particle-analytics.com>.

If the license server has been already installed:

1. Go to Windows **Start Menu** and inside the **Iota** folder, click on **License Registration** icon.
2. After a few seconds, a new tab with the **hostname** of your machine and some instructions will be open in your default web browser. **Ignore** the instructions and **close** the tab.
3. Open with a text editor the file **config.ini** located inside the **`AppData\Local\ParticleAnalytics\Iota`** folder located at your home directory (e.g. `C:\Users\Stephen\AppData\Local\ParticleAnalytics\Iota\config.ini`)
4. In the section `[DEFAULT]`, replace the file path of the variable **licence** by **port\_number\@server\_IP** information of your license server (e.g. `licence = 5053@172.16.254.1`) and **save** the changes.
5. Go to Windows **Start Menu** and click on **Iota Jupyter** icon to launch Jupyter Notebooks and start creating a new iota notebook.
