# Downloading latest Trust1Connector

## Downloading Trust1Connector

The T1C JS SDK no longer has a method to download the T1C installer.

Instead, the T1C installer can be downloaded by navigating the client browser to the `/v3/downloads/installer` endpoint of the Distribution Service (e.g. `https://acc-ds.t1t.io/v3/downloads/installer`). The Distribution Service will analyse the `User-Agent` header and automatically initiate the download of an OS-appropriate installer of the latest configured version. The user agent string parsing is considered "best-effort"; as they can vary wildly depending OS and browser software.

Alternatively, you can also initiate the download of a T1C installer with the following endpoints:

1. `/v3/downloads/installers/{{OS}}`: This endpoint allows you to specify the OS for which you wish to obtain an installer. The possible values are `win32`, `win64`, `unix`, `macos` `macosarm`. 
2. `/v3/downloads/installers/{{OS}}/versions/{{version}}`: This endpoint allows you to download a specific version of a T1C installer for a specific OS.

{% hint style="warning" %}
The automatic user-agent detection does not differentiate between ARM/M1 and Intel Mac devices

## 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://t1t.gitbook.io/t1c-js-guide-v3/v3.3.0-1/core/downloading-latest-trust1connector.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.
