# Prerequisites

Before installing Chromatics, please make sure your PC meets the following requirements.

## System requirements

* **Windows 10 or Windows 11**, 64-bit.
* An internet connection for the initial download and for update checks.
* The **RGB software or SDK** for the devices you want to control (for example Razer Synapse, Corsair iCUE, Logitech G HUB). Chromatics talks to each vendor's SDK, so the vendor's software still needs to be installed and running.

## Required runtimes

Chromatics 4 is built on .NET 10 and uses the latest Microsoft Visual C++ redistributable.

* [**.NET 10 Desktop Runtime (x64)**](https://dotnet.microsoft.com/en-us/download/dotnet/10.0)
* [**Microsoft Visual C++ Redistributable 2017–2026 (x64)**](https://aka.ms/vc14/vc_redist.x64.exe)

## Supported devices

Chromatics supports a wide range of RGB devices from Asus, Cooler Master, Corsair, Logitech, MSI, Novation, Razer, SteelSeries, Wooting, OpenRGB, Philips Hue, PlayStation controllers (DS4 / DS5), and LIFX.
