# Installation

### Register your account

Do this once on first use.

1. Open the loader.
2. Press `Register` below **Login**.
3. Enter your `Username`.
4. Enter your `Password`.
5. Enter your `Cheat Key`.
6. Press `Register`.

### First load

1. Log in to the loader.
2. Confirm your active subscription appears.
3. Press `Load`.

You should see a restart prompt.

Restart your PC when it appears.

{% hint style="info" %}
If no restart prompt appears, restart manually and try again.
{% endhint %}

### Second load

1. Open the loader again after restart.
2. Log in.
3. Press `Load`.

Expected behavior:

* The loader closes on its own.

If the loader stays open, injection failed.

Wait a few seconds, then try again.

{% hint style="warning" %}
If it still stays open, recheck antivirus, anti-cheat, and Windows security settings.
{% endhint %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.softaim.gg/draft/rainbow-six-siege/viper/installation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
