# Installation

Install ASIST and open it for the first time.

**macOS**

1. Download [ASIST-arm64.dmg](https://github.com/nyosegawa/asist/releases/latest/download/ASIST-arm64.dmg).
2. Open the dmg and drag ASIST to the Applications folder.
3. Open ASIST from the Applications folder.

ASIST is notarized by Apple, so it opens as is. If macOS asks you to confirm that ASIST "is an app downloaded from the Internet", click "Open".

ASIST downloads new versions by itself and installs them the next time you quit it. See [Updating and uninstalling](https://asist-agent.com/en/docs/start/update/) for details.

**Windows**

1. Download [ASIST-Setup-x64.exe](https://github.com/nyosegawa/asist/releases/latest/download/ASIST-Setup-x64.exe).
2. Open the downloaded file.
3. If Windows says "Windows protected your PC", click "More info", then "Run anyway".
4. The installer installs ASIST and opens it. From then on, open ASIST from the Start menu.

The ASIST installer is not signed yet. Windows SmartScreen therefore warns you when you open the downloaded installer.

The installer does not ask for administrator rights. It installs ASIST for the current user only, into `%LOCALAPPDATA%\Programs\asist`.

ASIST downloads new versions by itself and installs them the next time you quit it. See [Updating and uninstalling](https://asist-agent.com/en/docs/start/update/) for details.

> [!WARNING]
> ASIST cannot be installed on Windows with Smart App Control turned on, because it is not signed. You can check its state under "App & browser control" in Windows Security.

When it opens, the [first-time setup](https://asist-agent.com/en/docs/start/setup/) begins.
