his page details how to download and install the Chaos License Server for Chaos Arena.
## **Overview**
---
Chaos Arena requires a [Chaos License Server](https://docs-chaos.atlassian.net/wiki/spaces/LIC5) running on a machine in the network, accessible by the [Arena Server](https://docs-chaos.atlassian.net/wiki/spaces/ARENA/pages/125275350) and all [render](https://docs-chaos.atlassian.net/wiki/spaces/ARENA/pages/125275350) and [operator](https://docs-chaos.atlassian.net/wiki/spaces/ARENA/pages/125275350) machines.
To be able to run Chaos Arena, you need the following licenses to be active in your Chaos account:
- A single Arena Server App license is required for the server application.
- One Arena Render Node license for each render and operator machine.
The machine where the license server is installed must be connected to the Internet at the time of installation and activation of the licenses.
Offline (borrowed) licenses can be very useful to avoid relying on constant Internet connectivity. More information can be found here - [Borrowing Licenses for Offline Use](https://docs-chaos.atlassian.net/wiki/spaces/LIC5/pages/125050233)
After borrowing licenses for offline use, the license server machine can be disconnected from the Internet and connected to the network where the rest of the machines are connected to provide licenses for all other nodes.
## **Installation Process**

##
**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
```
## **Troubleshooting**
---
If you have difficulty installing or running the Chaos License Server, please refer to the [Troubleshooting](https://docs-chaos.atlassian.net/wiki/spaces/LIC5/pages/124392984) page.
