This page details how to download and install the Chaos License Server for Chaos products.


## **Overview**

## **Run Chaos License Server installer safely on macOS Catalina and later**

---

In macOS Catalina and later, when an app fails to install because it hasn’t been notarized or is from an unidentified developer, it appears in **System Preferences** > **Security & Privacy**, under the **General** tab.

Click **Open Anyway** to confirm your intent to open or install the app.



The warning prompt reappears, and you can click on **Open**.



The app is now saved as an exception to your security settings. From then on, you can open the app by double-clicking it, just like any authorized app.

*For more information, see Apple's **[How to open an app that hasn’t been notarized or is from an unidentified developer](https://support.apple.com/en-us/HT202491)** article.*


## **Silent Installation**

---

A silent installation allows you to complete the Chaos License Server installation without running the installer's GUI. To complete a silent installation, run the installer via command line:

```
cgls_win_6.0.0.exe -auto
```

This installs the license server with the automatic preferences and accepts the [EULA](https://docs-chaos.atlassian.net/wiki/spaces/LIC5/pages/125308861).


If you want to specify a custom installation directory or choose not to add firewall exceptions, run the installer with the following command:

```
cgls_win_6.0.0.exe -gui=0 -quiet=1
```


The ***-quiet=1*** argument automatically accepts the EULA. You can then select an installation directory and choose whether to include firewall exceptions.
