# Installing

> Download Oink for Linux, Windows or macOS, install it and activate the free alpha licence.

Download Oink from [oink.megasupersoft.com](https://oink.megasupersoft.com/#download). Each download has everything it needs: its own Python, colour management, fonts and FFmpeg. **You do not need Blender.** Blender is an optional extra, see [Engines and the Blender bridge](/docs/concepts/engines).

## What you need

| | |
|---|---|
| Linux | x86-64, glibc 2.34 or newer (Rocky / RHEL 9, Ubuntu 22.04 and later) |
| Windows | Windows 10 or 11, 64-bit |
| macOS | Apple Silicon |
| Graphics card | OpenGL or Vulkan; every node runs on the GPU. The AI tools use an NVIDIA card; each model's graphics memory is listed in [AI models](/docs/reference/ai-models) |

## Install

**Linux.** Extract the `.tar.xz` and run `./install.sh` inside it. It adds the menu entries and the `.oink` file type, so you can double-click a comp to open it (each double-click starts a new copy of the app). `.nk` files are left alone.

**Windows.** Run the `-setup.exe` installer (it installs for your user, no administrator rights needed), or extract the portable `.zip` anywhere. The builds are not signed yet: if SmartScreen says "Windows protected your PC", choose **More info**, then **Run anyway**.

**macOS.** Open the `.dmg` and drag Oink to Applications. The first time, right-click Oink.app and choose **Open**, then **Open** again.

## Activate

The alpha needs a free licence. [Request one](https://oink.megasupersoft.com/#alpha) and the key comes by email. Paste it into the screen that appears on first launch. A licence covers two machines and keeps working offline for 14 days between check-ins; **Help > License...** shows it and lets you free a machine.

## Updates

The app checks for new builds and offers to install them; **Help > Check for Updates...** checks right away. Each build is checked against a signature before it installs.

## The AI tools

The AI nodes download their packages and models the first time you use them (several GB). See [AI models](/docs/reference/ai-models) for sizes and licences.

## Blender (optional)

Opening `.blend` files, EEVEE, Storm and Alembic through Blender need Blender 5.2 LTS. Anything that needs it says so and offers an **Install Blender (optional)** button; the rest of the app works without it.

## Logs

If something goes wrong, the logs are in `~/.cache/opencomp/logs` (Linux), `~/Library/Logs/opencomp` (macOS) or `%LOCALAPPDATA%\opencomp\logs` (Windows). **Help > Report a Bug...** collects them for you; see [Logs & diagnostics](/docs/logs-diagnostics).

## Licences

Oink is proprietary software (MegaSuperSoft, all rights reserved). The libraries it ships or downloads keep their own licences: see [Licences and source offer](/docs/concepts/licences).
