# 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.

The automatic user-agent detection does not differentiate between ARM/M1 and Intel Mac devices
